There are no schools for reloading, but yours comes close. Thanks you for your information. In reloading, as in life, there is no perfection. You should make your ammo as precise as possible, and enjoy this process at each level with pride. (that's my take away)

Excellent! For precision rifle hand loading, a standard deviation in single digits is a goal. Low standard deviation is the result of consistent ignition...consistent primer prep, consistent case volume, consistent powder ignition, consistent neck tension, etc. There is no human error involved like there is analyzing groups and subjectively ignoring some shots as "flyers".

I love this kind of stuff. I use the standard deviation as a learning tool with my pistol loads. I have learned a lot of general trends over the years and use that knowledge to initiate a starting point for a new load I'm working. My best pistol SD is 6. That was used with 4.4 grains of #2 under a 115 grain Xtreme copper plated bullet (9mm). My best rifle to date is 12 and that's with my 30-06. I use that primarily for deer hunting so I'm very happy with that. But it just amazes me how seemingly subtle differences can change things quite a lot. The aforementioned 9mm load, for instance, was shot out of my Shield. We shot the same load out of my son's shield and the numbers were quite different with deviations in the 20s. I'm just fascinated by all of that.

My 255 grain SWC with 6.0 grains Unique 45 ACP was pulling a standard deviation of 28 out of my 1917 revolver, but the same exact load was pulling 5.7 fps standard deviation out of my Tommy gun. Seems like some days we can work hard to get a load down pat that works well in one of our guns, but we can't make it work as well out of our others. The quest for the universal round continues....

kingduckford - That's a great point - barrel length, and quality of the barrel have a definite influence on powder burn with the same ammo. Would be good to do a comparison of a snubby vs 6 1/2" barrel and standard deviation. It's all about projecting how the population will perform under one set of circumstances in terms of deviation from the mean average. Change the circumstances and new computations have to be done for the same population... So, to tighten up the SD for even that factory 125 gr JHP magnum load in the video, I could run the loaded rounds through the Lee FCD to slightly tighten up the crimps - then retest to see if we could beat the SD of 41 in the same gun - or as you suggest, shoot in a different gun that might "like" that load better (lower SD).

When you say you want standard deviation of 10 or less for rifle loads at distance, what distance are you talking about? 100 yards, 500 yards, 1000 yards? I'm just getting into rifle reloading and it's good to know what standard deviations I'm shooting for. Prob & Stats finally comes in handy!
@haywoodjablomy1361

I would think that means "all of the above". If you can achieve an SD of 10 through the chronograph, (which is VERY close) that will assure consistent placement at distance. (well beyond the chrono) I think. :)

mrbriancnc - This can all be calculated for more precision, but as a general rule - If we shoot small groups at 100 yards with ammo that has SD higher than 20, vertical dispersion at 600 yards will miss the target somewhere around the order of one shot out of three. If less than 10, we will be in the 80-90% hits I once had some factory ammo that shot SD of 8, and that is not easy to match, much less beat...Best to ya, FC

Just for reference, Factory rifle loads generally produce an SD of around 20. If you intend to shoot at less than 400 yards, anywhere between 20 - 15 would probably be sufficient. Beyond that distance you would really want to be single figures. Lower SD figures really come into their own at longer ranges (as long as the shooter does his / her bit.

Hey FC 45LC, Will be casting and loading .38 spl soon, using 146 to 158 gr. Would like to know if it's typical to purchase the "Lee" bullet sizing die for these grain bullets? Also powder coating most. Which size die .356 or.357? I'm new to the .38 and .357. loading.
@kingduckford
8 жыл бұрын
Can't answer for the Lee resizer, but you'll be wanting to use a .358 sizing die, .356 is for 9mm, so that 9mm bullets will be sized .001 over from .355 to .356, so a .357 should have a resizing die of .358, a thousandth inch bigger is desirable. Now, if you are shooting an old revolver, its worth thinking about slugging that barrel to get an accurate read of your dimensions, some older guns are a bit bigger, and require bigger bullets and a bigger die. Again, standard would be .358. Undersized bullets are our enemy, poor obturation leads to poor accuracy and severe leading from gas cutting.
@FortuneCookie45LC
8 жыл бұрын
Dean Hudson - As kingduckford says - good starting point is .358" bullets for 38/357 - no need to do anything else if your bullets shoot well, long and clean...Size 'em to .358 if you need to size 'em at all. Even if your final bullets are .359 - .360 after powder coating, you don't have to size 'em back to .358 unless they don't feed into your revolver or don't shoot well. Come back with further questions if you find need... Best to ya, FC

When working up a new load......how many rounds do you recommend for chronographing for best results, 10 rounds, 20 rounds, ????
@FortuneCookie45LC
8 жыл бұрын
Cmax Arms - I know you know the following things, but newer shooters may not...1) Standardize your rifle - It is all set up in the way it will be used (i. e. stocks, rests, bipods - stock and sight screws snugged up, cleaning regimens) 2) Determine the use for the rig. hunting means accuracy for maximum performance range allowing clean humane kills of majestic game animals - and then setting own personal effective range to allow for field conditions = less than the maximum range possible. Varmint hunting - same as hunting, but much more accuracy needed with enough power to allow chosen bullets to explode small critters at distance; tactical = humanity issues are out the window - get damaging hits and wounding puts much more pressure on adverse societies; target shooting = accuracy is everything and, unlike hunting, terminal ballistics are irrelevant . 3) Assemble and narrow down the choices of components you wish to work with 4) Load (power determined by accordance with reloading manual data,) and shoot the ladder (5 round groupings with incremental powder charges) = 5 round groups are sufficient to note where the accuracy nodes are for your barrel harmonics = cleaning regimen should be done, but it is your choice to follow as long as fundamentals are included. 5) Narrow down the ladder including work with bullet seating depths to fine tune accuracy with that bullet and powder combination. If 4) and 5) don't yield desired results, or if the shooters simply wishes, then go back to 3) with different bullets and powders. Chronographing can be done during 4) or 5) with tweaking to reduce Standard Deviation for distance accuracy. Note: benchrest shooters work with 20 or so rounds of brass at a time out of their same lot brass. Varmint shooters need to be able to shoot over 100 rounds of ammo out in the field (we used shorter range rifle and a couple of longer range rigs to spread out the wear and tear). Including shooting to get fire formed brass, we can shoot out the 1500-2000 round accuracy life of a barrel just working up loads (depending on the caliber chosen - 220 swift shooters suffered here). Good shootin' to ya, FC

Haywood Jablomy Heavy crimps cut the case life considerably. I load for a lever gun (Win 1873) at high pressure (21.0 gr. of W296 with a 125 copper jacket), and trim the case, and crimp consistently. They chrono at 2050 fps, but I won't shoot them in my SW revolvers (19, 66, 686). Oh well ... I love the sport! As long as you don't blow the top off of your revolver, they are safe.

*"As long as you don't blow the top off of your revolver, they are safe."* [[[SHUDDER]]] Had an acquaintance once,(an LGS owner) that practiced just that. He'd don welding gloves, wrap his arms around a tree and fire. If the gun didn't blow up, that was his "starting" point and he'd work "down" from there. Witnessing that probably delayed my adoption of reloading by a decade. Bought a black powder pistol off him and "experimented" with that instead. lol
