( there is a local built induction annealer I want to get next year). Lube, bump size 1000th. Expand and wash cases again. Prime using the press, throw and trickle powder. Seat bullet and voila. And no, not been loading for decades, just did my 1st batch of once fire cases today actually. Doing a quick ocw test next. Maybe one more club match than entering Nationals, my goal I to finish in the top 50%. PRS. Have only done 1 club match thus far. But hey, go big or go home

I believe some of the old BR theories on priming may still hold true. The problem will always be with the primers tolerances themselves, and we can not control primer manufacturing. We can now uniform cases and primer pockets very consistently, and could develop tools to uniform and measure pockets to case base or rim top. However, when I (and others) have measured primers there is significant inconsistencies. For example, I have measured CCI BR4 and Federal Match LR primers. Both cup height and height from cup base to top of anvil measurements can vary by several thousands of an inch. In addition, there are variances in the priming compound pellets. This why I feel that seating by feel may currently be the only way to get reasonably consistent crush. It takes practice, and slight variances in primer to cup tightness sometimes makes this tough, but you can often feel first contact. The problem is there is no way to confirm or measure this except with the substitute measurements of velocity and accuracy, which are affected by many more variables. I use Sinclair and 21st century hand tools with great feel. It also appears that the Primal Rights CPS is built very well and should allow great feel, although I haven’t tried it yet. I am no expert, and am not in the same league as either of you, but it does not seem possible to have consistent crush with a set/controlled seating depth due to primer height inconsistencies. Just to be complete, I am aware that K&M does make a hand primer seater with a gauge (kmshooting.com/product/primer-gauge) that measures the depth of each primer pocket and each individual primer height during each primer seating operation to allow “precise control” of depth. However, this seems like it would be a very slow and arduous process, so I have not tried it. These are the rabbit holes that make the sport interesting and cause headaches. What does matter and what doesn’t…the world may never know. However, Eric does a great job testing and discussing options to inform his readers what seems to truly affect results and what just makes us feel better. Thanks to both of you. Best wishes.

I call BS! How does uniforming the primer pocket within .001” matter? What matters is the primer being fully seated (to prevent the primer moving forward when being hit with the firing pin). Primer pocket must be clean of residue so it seats fully. Fully seated primers fire directly into the flash hole (and do not flash under the unseated primer before traveling down the flash hole). Primers deform easily while being seated so make sure your seating method has a STOP to prevent over seating (meaning squashing the primer in the primer pocket), I use a Frankford Arsenal Hand Seating Tool. You can feel went the primer bottoms out in the pocket, then set the stop at that point. I measure my primer seating depth with a dial caliper from case head to seated primer and they range .004”-.005” depth. I’m my mind, cleaning the primer pocket and flash hole is essential. Uniforming the primer pocket is useless.

So much information! Easy to get lost! I noticed an improvement when I stopped using the hand primers and began using the press to load primers. Same press and same shell holder, ever time. Important to remember these guys are chasing myth like results, with ridiculously expensive 25 lb rigs, at incredible distances! If you're just a weekend warrior (like me) and chasing 1000 yards, or even a mile, just go shoot! The best thing I ever did is clear my bench from all the unnecessary tools. My results compounded fast when I stopped chasing the internet shooters. I was stuck at 300 yards thinking I needed to trim, turn, unify. Then you get into concentricity gauges, and comparators. Nope! Just wipe the lube off and go hit targets! Find a load at 100 the gun likes, then go right to 1000. Then teach all your buddies. There is no need for any other BS unless you need better than sub 3/4-1 MOA groups at 1000 or a mile. Learning the wind is way more important, seeing your misses is way more important, your spotter is more important. Stop loading and start shooting! Then, circle back and become an F-class LOADER.

All of this is based on the primer after manufacturing. Trying to reduce variance within the reload, However, sadly, there is still variance within the materials that make up the primer compounds, uniformity of the primer components, reducing the distortion of the primer while seating and the hardware within e.g. anvils, etc.,. I'm not sure I buy all this and while I understand what Greg is saying, I think he's creating a market for a problem that doesn't really matter. Perhaps to pro shooters, trying to finesse a half of percent of performance in their loads. It seems to me, the energy should be focused elsewhere, such as the uniformity of the Meplat and Ogive. My two cents. I don't think people will be turned off, some just won't care. How many professional shooters are measuring the primer pockets after each firing? I'd like to see some hard data that substantiate the difference.

I watched a video last night on this very subject. The host did all the primer measurements, segregating primers, and all the other time wasters and then shot the cartridges and found no difference whatever. The only thing necessary is to avoid not seating the primer to the bottom of the pocket. You can do this with an RCBS bench mounted tool. Until he gives the empirical evidence by actually shooting and showing how much difference it makes, I will remain an infidel.

Hey Eric... By 91' myself and some customers I wrenched for, were shooting 100,000 rounds a week... more for some, less for others. (From here on I can only speak what I did ). Pistols mainly, shotguns, and rifles. Shooting that many rounds, all I loaded on were Dillon 1000's, 1050's, a 650, and the 900 when it came out... yes I have Wilson hand dies, boxes of j4 jackets, 275# of core material, and all the hand made things like the press for the jackets and bullet turning lathes all made by Red Cornellison and Sam Lair from way back...and custom dies made using the reamers I cut the chambers with... Skipping to the point... I measured the cases in Tool and Die at an airline in Tulsa where I worked, and at McDonnel Douglas where other friends worked. Sooo, in the end everything you have talked about here, was gone through and an anal bit more. The results... depending on mfg. of the cases, rim thickness & pocket depth, and primers on anvil height, feet angularity, softness as to brand ( I shot .38 Super, and used small rifle exclusively) and to shoot them all buying 5000 to a pallet of primers in the last 40 some odd years, .002" crush or preload is what the average took, to load one lot number to the next. After an elephant ass load of rounds, none ever misfired in practice or matches. In all fairness though I had ONE failure to fire with my son years ago because I had been given almost 7500 rounds by a friends widow, and I grabbed a handful out of the shin high ammo can... should have known, lol. I realize it's not the guns or the games you guys shoot, but we are talking primers here right? By the way... I still have over 400 cases of 205 match too... and that pallet... 1/2 full... it's sickening what their ( still don't know anyone who voted for Tweedle - dumb and Tweedle - dumber... being reverent for your YT pod and channel ) president has perpetrated against us all... Oh yeah, the guns we shoot, can hang... and only in extremely rare cases due to mfg. bidenism, have those discernible measurements seemed to matter a great bit. But solely being in the power filled cartridge game... it probably is worth checking. The guns never coughed, were more accurate than 99% of the guys and gals could shoot, and that, proves, everything I did check... contributed, right? Thanks Eric, I always enjoy the content, sorry for the length. Talk to you soon, Sincerely, Seth

Ever since I've watched a few of these videos while doing brass prep I've got on the bandwagon of doing absolutely nothing with primer pockets or flash holes. Hell most of my 6.5 Creedmoor/Grendel and 6mm ARC I barely clean the brass and I don't see any differences between that ammo and my old ammo when I was doing everything under the sun with it.

Hi Erik, very interesting subject. If I understand the real problem is the rim thickness that is unconsistent. So the best solution is to uniform these rims with a lathe or a special tool. So uniforming primer pockets can improve or not, but it won't ruin anything ! He also forgets that because of the pressure brass flows into the primer pocket (especially on the 3-4 first firings), and the primer pocket will preserve the same pocket size with square corners at the bottom.

Bull hockey. When I uniform my primer pockets then seat the primers, I measure both from the bottom of the case. Also I set or adjust my primer tool to this depth adjustment as my primer tool is adjustable to an extreme adjustment to a .0005 measurement and all are at to a uniform .004 or .0045 in depth from the base of the case. An industry standard. My primer system is bench mounted with a feed and can use a couple different brand or primer trays used for the hand held models. I modified my off press priming system so I can do this adjustment to every batch of brass weather I cut the pocket uniform or not. It also built in an adjustment for centering different brands of shell holders. However some pockets are just to shallow to get .004- .0045 with out cutting them or informing them and others are really good. This is with pistol or rifle and has giving me more uniform extreme spreads and uniform extreme deviation standards. Sometimes the primers change just a little from lot to lot consistency in hieght size which can force a depth change set up and can change from brand to brand. And yes rim thickness plays a big part in this adjustment but when setting the primer tool measuring from the bottom of the brass and using a same lot of brass and primer the measurement only changes .00005 to .0005 in depth which is very consistent. Priming with an unadjustable primer system will never achieve this kind of accuracy by feel.

I think Erik stumbled on that bastard gremlin that creeps into every reloading room. It's not that important for the variance of bullet weight, or primer pocket differences, etc. Now, I am going to quote Erik here, "Consistency is useless if you're looking at the agg." Well, if we go by this mantra (which is undoubtedly only attributable to Erik) we must also state (as the 15th rule of universal thermodynamics) that the aggregate between primer pockets, bullet weight variance, butterfly farts in China, and temp variance in powder if we are to be completely honest with each other. :) Damn fine video guys. These are the discussions we should all be having. Such a vast amount of experience and knowledge here. I actually cut the pocket back out post firing with a thinger jigger that goes all the way into the pocket and cuts just the bottom of the primer pocket. I have no idea what the tolerance or variance is on this TJ (Thingy Jigger) but it will only work on a fired case and it takes maybe a .0001" of brass out of the pocket. I prime on a Dillon and make sure to really crush the shit out of that little booger just because that particular case pissed me off last week by causing a flyer. Yes, I sort my cases by what pisses me off with a flyer and which ones don't. #lapuarocks

When I was home in December I did some ladder testing with a .223 and .308 Rem TAC (not a precision rifle but pretty accurate). I wasn't happy with what I was getting, probably because I was chasing the lands, but I ran out of time. I'm moving back home and plan to pick up where I left off. I use a Sinclair hand priming tool and it's been good. I've also been cleaning pockets (not on my Lapua brass though). I like what I'm seeing on the Primal Rights site for higher round count priming. It looks like I can use my Dillon primer tube filler with it as well as the Lee Lee Autoprime shell holders. I generally load 5 for each powder charge and 5 different charges for sighters and a ladder test at 200.

At which point the firing pin travel is important, is it worth it to uniform the rims thickness or sort the primers ? I will try to modify an headspace gage to measure the case from its shoulder to the primer, sort some cartridges by this measurment and take the velocities to get an answer.

Uniforming primer pockets is not important. Having the same depth in all your primer pockets is not important. Here, buy my $600 priming tool and seat primers in inconsistent pockets. I'm lost. Oh and ruining your brass from uniforming? Other f class shooters are getting 20+ firings while uniforming. So how is it ruining the brass?

@@buick4622 it's normal to get inconsistent primer seating depth if the primer pockets aren't the same. If you have more or less friction between the primer cup and the primer pocket (diameter, shape), it will resist more or less to the seating operation ---> inconsistent seating depth. I' ve made some tests that shown that this inconsistency comes mostly from this difference of friction, from the primer pocket and not from the primers. You can allso check and see that even with the same depth setting on the tool, if you seat the same primer again and again the primer will seat deeper and deeper each time. A solution could consist to sort your brass by primer seating depth.

If all the measurements are not the same. And I mean all. Your pissing in the wind. I deal with less than .0002 on machine work. so if you think that a primer is this consistent when is built your up in the night. The firing pin will have to hit it at the same depth from which it is seated first off. Just as you stated. Next the primer has to be 10000% correct when it is built. All dimensions. Including primer hull thickness and tensile strength. Other wise when the firing pin hits the shell it Shall be inconsistence. Where does it end.

Well, if you deal with 0.0002”, then you understand that everything has a tolerance. If you do a test and figure out that you have 0.004” tolerance in primer seating depth where rifle shoots best, it’s not hard to seat it in the center of that “node” and maintain good accuracy even though the tolerance is large. With such large tolerances in components, it’s more important to test and find the center of the node so that the tolerance don’t stack against you. B

Ensuring primers are bottomed out, thus having adequate anvil compression and having de-burred flash holes should be good to go for the avg reloader. Myself having encountered situations were a certain brand X of primers and type X brass cases would cause primers to not seat below flush without resorting to abnormal seating forces (noticeably indenting the primers). Thus began my journey with primer uni-formers to render case primer cup depth to within SAAMI specs (0.125 to 0.132) for a large primer; however, I had always assumed as per the SAAMI dwg that the base of the case was the reference point. However, here it mentions that reference datum is the top of the rim not the base of the case head due to manufacturing process! Anyone have ref, video links, etc on that specific portion of the manufacturing process?

You're on the right track of busting this grift. All other brass prep registers off the face of the case head. There is zero need to overcomplicate when SAAMI specs allow 8 to 13 thou tolerance deviation and manufacturers say that's good enough.

I understand trying to get the best absolute zero in tolerances, but how much does it really matter? Erik has said he will change his barrel if it opens up to a 1/4 MOA, for 99% of shooters, Learning to read the wind would be a better use of their time. But, Really, I'd like to see groups shot with every variable at zero, then change the primer depth .001 and see what the groups size difference is. For the 99.99% we'd never know if it was the primer, wind, use, etc. Basically I'm saying there is perfect, realistic, Professional(Erik), Combat effective, beginner, and DPRK. Don't get me wrong, I'm not complaining Erik's content is amazing, I just want to see the difference it would really make. I already shoot Lapua Brass and have never taken reloading to this level of concern, because if I miss I'm gonna blame myself anyway.

Real machinists probably don't toot their own horn enough but I know and I bet Erik knows when we meet a real one. It's very hard to call yourself a machinist without formal training. All of my training was informal. I think Erik has had some formal training but very specific. If you don't humble yourself in the machine shop, someone will do it for you.

I'm sure if primer seating depth was important then benchrest shooters would have been talking about it years ago. One thing he's not considering is the depth of the brass through the flash hole area of the base. Next we'll have a tool to machine the inside base of the case.
@jonathanjones4979

Doesn't the base of the case seat on the bolt of the firearm? Additionally, have you taken into consideration fluid dynamics of propulsion? I'm not a long range shooter but I would think the primer pocket and flash hole would act like a rocket motor. as long as you have reliable ignition and accurate alignment of the flash hole through the center of the powder (fuel) charge then you would have the most uniform and consistent burn of propellant. Also, aren't there variances in primer cup uniformity that may lead to variances in angle of alignment of the primer in the pocket? Again, I'm not an expert but I am curious as to what your input or thoughts might be on this theory I have.

I would recommend him having some published independent testing. I apologize if this is already been done and I'm missing it.

WELL, I SOLVED THE RIM THICKNESS PROBLEM. That is why I developed something specifically for the CPS that does not effect the headspace or anything else. I now get primer seating depth within .0005, that is five ten thousandth of an inch no matter what the rim thickness is. I told Greg this and he told me that only maybe one percent of people worry about rim thickness. I find that extremely hard to believe. Why would someone want to prime a bunch of cases , say 100, and then have to sort them by primer seating depth and be left with maybe 50 cases that are within .001 and the other 50 you use for something else? Instead, with my mod for the CPS they will ALL be withing .0001. I call BS. So eventually I am going to release the plans for anyone to do this to their CPS.

17:50 you mention reliable ignition. How do you measure the ignition, and how can you determine consistency of ignition? If there is no reliable way to measure ignition, and to know the factors related to its impact on accuracy, the entire discussion becomes moot. That is, match winners will be right, and match losers will be wrong. But why? I think the machining answer would be to have primer pockets with a ledge in them, which would stop the bottom rim of the primer cup, and include a preset depth to the bottom of the primer pocket, sufficient to provide your desired anvil "crush" number, which you said you want at about 0.002". Then you could eliminate variation due to primer seating friction on the side of the primer cup, since the degree of tension would not change the ultimate seating depth of the primer and anvil. A manufacturer, such as Alpha, would need to produce cases with cut flash holes, then the end user would need to use his personal primer pocket cutter to finish the job, indexing the cutter off the flash hole as "center". Then your primer pocket cutter would function as a primer pocket uniformer, indexing each time off of the flash hole as center. Perhaps the primer pocket cutter could include a flash hole cutter on its nose, and you could chuck the cases up individually, and cut your own flash holes and primer pockets. That would make it easy to get a manufacturer to provide test brass, since they already have a metric ton of cases without flash holes and primer pockets. Yeah, do that and get back to me. I think I want one cutter that cuts flash holes plus primer pockets, and another that just has a centering rod in the primer pocket cutter, so I don't risk wallowing out my flash holes; and guys that want small primers and small flash holes can use a different cutter than guys that want large pockets and large flash holes. If we do this, the only real variable in ignition for a given rifle is the internal construction of the primer. To work on this, you're going to have to talk to the lady in Lewiston that puts your primers together. I suspect that aspect is as good as it can get already, though.

I'm calling you out on this. Even Lapua brass has at least .005 variance in primer pocket depth. So now Greg said rim thickness varies up to .005 also and I agree. So if you were to uniform your primer pockets to say .131 deep they would ALL be .131 deep, as opposed to .129.5 to 131.5 as Lapua comes. So now all your primer pockets are .131. How do you get off saying you are introducing more variance. You are STILL and always will be at the mercy of the rim thickness, no matter how you look at it. So Greg, even with your CPS and your Primewhere, which I own both, you are still indexing off the top of the shellholder. So, in reality, if you were to leave it alone and NOT uniform your primer pockets, you would have the variance of the rim thickness PLUS the variance of the primer pocket depth!!! After uniforming the primer pockets you only have the variance in rim thickness!! Better to have only one variance than two. Think about this long and hard. You are mistaking my friend.

And how many people have seen their accuracy improve by using a mechanical primer seater that doesn't do the primary job - seat the primer to the base of the primer pocket. The CPS tool cannot beat a hand primer seater. It just cannot. Mechanical advantage hides the feel. With a hand primer, you cannot bend the rim. No way. But good try with selling a product. When I see competitive shooters (I am one) get an actual advantage on target, consistently, from using a tool like the CPS primer seater, I'll be a convert. There is so much BS in this sport, it's just not funny.
