Thank you very much. I just bought the same gun and the Huma pin probe with it for slugs, just the probe not the power kit. And I was laughing the whole video to myself about the one part I wanted to try required entire disassembly of the gun, but I was pleasantly surprised at the end that actually nothing needs to come apart at all, just one screw. But now I know the procedure and it's really straight forward.

I have found that the hammer that comes with the slug power kit is simply to heavy and over powers the rifle, so far i have only had success with 33g and 36g NSA slugs but they dont sell them here in the UK.

@@PaulHamM3 I got the .22 cal with a 600mm barrel, so I guess it's not exactly the same. From what I have heard, and this makes perfect sense, because too much air after the slug leaves the barrel is just problems, is that with the heavy hammer, you want your reg at 160 and shouldn't go below 150 or the valve just gets held open too long, My guess is that you'd probably be looking at closer to170 with the 500 mm barrel. You would have more leeway with the 700 since it takes longer for the projectile to get to the end. Plus, Youd be getting all the benefits from the entire package. I appreciate you putting that information out there, because it leads to more investigation and in turn, better understanding. The stock hammer weight isn't able to push open the valve at 160 bar, enough, for big gains, so the upper limits of the stock set up, is entirely hammer spring, hammer weight, and reg pressure related. One person claims to be achieving 0ver 70 fpe from their .22 Crown mk2. That's got to be putting you close to 90 I would be imaging in .25

@@PaulHamM3 I was hoping to be able to shoot the 26 grains in the 900-fps range comfortably, so if this pin probe is a free 20-30 fps in the higher power limits of my stock set up, it worth the extra efficiency, and a step in the right direction if I go further, down the road.

@@ravenshield7823 so i have my 600mm .25 crowns Gen 3 Huma reg set at 160 bar and im pushing a 36g NSA slug at 890fps with the transfer port set to high and the barrel port turned to slug, so i dont think you will have a problem getting a 26g slug up to 900fps. I have read that a few people say they are getting there crowns at 70ftlbs + but i think they find there hammers are getting wreaked, its just to much power for the crown and i dont believe FX designed this gun to shoot slugs at high velocitys. that being said, i see the south African youtube boys getting good performance out of there .22 crowns and slugs.

@@PaulHamM3 Ya I think your probably right, it's expensive and I was well aware of it's 50 fpe rating when I ordered it, I personally have no need or desire to push it beyond that, and, I have had really good results out to 175 yards with my Redwolf even at a modest 855 fps with the 26 grain, so more power for me isn't the answer, but free power is a bonus so I settled on just the probe figuring I could actually back away from its limits while not really losing anything. I ordered it with the Heavy liner, 1/16 twist, and thought I might have bracketed myself into heavier slugs than I actually wanted to use but I think it will be perfect. FX heavy liner is stated on their site to be required for 23 grain and up, so I hope I made the right call. Thanks again for the tutorial, and I wish I knew how to help your situation.

I don’t understand why you take the trigger and hammer out. There was no need for this. Stil informative as to how to install but why would a gun that operates with no hammer weight whatsoever benefit from a 26.5 gram hammer weight. Could you share any of your experience with lower, more realistic hammer weights

I installed the hammer weight because that was what FX sold,clearly they havent done there homework as the hammer weight that came with there own FX crown slug power kit was way to heavy and just over powered the gun and made it very erratic. If I remember correctly I decided just to use a hammer ( no hammer weight) that bagnall and kirkwood supplied me which was slightly heavier than the FX factory hammer and also harder as winding up the hammer spring tension caused damage to it.

The slug power kit comes with a pin probe that can be sleeved so the probe fits .30 cal, i have no experience with .30 cal but i would take a educated guess and say that putting in a heavier hammer weight will definaitly increase your velocity, try the hammer weight that comes with the kit but be prepared to experiment with lighter weight ones as i found the 26g tungsten weight to heavy.

I found that fitting the tungsten hammer weight that came with the slug power kit severly over powered the rifle and made it extreamly erratic and inconsistant, so now i am currently experimenting with different lighter weight weights as i belive the 26g tungsten weight should only be used in the fx impact to power heavy, high velocity slugs . I fitted a new style hammer that weighs just 2grams heavier than the factory hammer and that gave me a extra 20 fps, just a case of experimenting mate.

So I just got my kit and the hammer weight and end cap are a perfect fit, but on the MK2, the adjustable probe shoulder hits the magazine and would require tooling it back about 3 or better millimeters. So the only thing you can use is the weight and end cap, which will come in handy when selecting different hammer weights to try but otherwise kind of a waist. I wonder if this probe would even work in the original crown since I thought all those parts and dimensions were identical.

@@PaulHamM3 Yup, I did the exact same thing but then found it wouldn't close all the way, so there must be some differences that's evading my imagination, because I can't make any sense of it, no big deal since I actually like the pellet probe and don't really think it's a limiting factor, I actually think it's better since it's been said by Dubber that the pin probes, can seat the pellets a bit crooked sometimes. I've been nothing but impressed the accuracy of this gun so far, 155 bar, it was shooting the 21 Barracuda match, the 25.4 Redesigns, 26 Griffin slugs and the 27.5 NSA amazingly. 600mm heavy liner, the pellets were not speed fussy, but the slugs shot best on max, and those speeds at my settings are 930 for the 26 grain Griffins and 900 for the NSA 27 grain. I was perfectly satisfied with the accuracy at max, but I really don't like the Idea or feel of the hammer spring being maxed out like that, preload is maxed also. I could get another 15-20 fps at 150 bar but lose some efficiency, So I need to up the hammer weight. I installed it this afternoon and will be able to test it tomorrow. I backed way off the preload for now just in case as I have heard the hammer weight is a bit too heavy. I have a 6-gram weight on the way from Bagnell and Kirkwood but that will take 3 weeks to get here. My MK 2 had a wear bushing on the stock spring shuttle which I could put on the new hammer weight, but I left it out of the mix for now. It's something I Haven't seen in any install video but adds about 2 more mm of preload. I don't think I'm going to need it if this weight gives me decent SD's, I backed off to 140 bar and will start testing there and see where the current loose preload will get me with just the power dial and increase the bar pressure till the velocity stops increasing just so I know I'm preload limited and not overpowering anything. I'm not sure if it was speed that gave me the accuracy I was getting at max with my two slugs of choice or just the tune it was at, But it clearly favored the most I could give it, which is something new to me, usually when I back off of peak things tighten up, so I'm guessing, if I could give it more, it will reward me, to a point, but I'm only looking for about 960, with the 26 and 930ish with the 27.5, with left over spring so it's more relaxed and the sear isn't chewing into the hammer. I will test and give you my results tomorrow, and what it took to get there, or if I can't get it the way I intend to, I will share my thoughts on why I think it didn't work.

@@PaulHamM3 Well, things over all went very well, although you reach a point of diminishing returns quite quickly with the 600 mm barrel, I was able to get the velocities I wanted without really stressing anything. This valve has no problem with the added hammer weight, I don't think it's ever going to be an issue. I stopped trying to get any more at 54 fpe, which gave me a nice bump in velocity for the 27.5 at 940 and the 26 griffins at to 960, but I will shoot them at 940 where they are performing epically, same with the NSA, probably my go to for out to 200 yards. The 25.4 redesigns are unreal also leaving one barely jagged hole at 43 yards at almost any speed, like 860- 940. Not fussy at all. 43 yards is a weird distance I know but I can use my table and tune from inside to my backstop, no bag rest just kind of half assed standing with a bipod. 3 perfect projectiles as far as I'm concerned. I have not tried the knockouts or HN slugs which everyone say are great out of the crown, but I don't need to since I have these two slugs that I don't really see how it could get any better. I brought my reg pressure up to 170 bar, and this had to be done to get the velocity and still be in the efficient zone. As far as I notice, as long as you are shooting the same velocity, 900 fps, let's say, it makes no real difference what the reg pressure is, you will still get practically the same number of shots, but the real difference is just how much quieter and smoother the shot is, and it's been my experience that the slugs always seem to enjoy the higher pressure and less volume of air. Maybe not in larger plenum guns but I don't know. I wound up adding some more preload just till the spring was inside the new shuttle, so it was always captured, just to prevent it from having to ride up the chamfer. On minimum, or setting 1, as it is now, and will stay, so I have a constant to start going by, the redesigns shot at 785, at setting 9, it just so happens to be 900, which is kind of cool and hard to forget, my velocity seems to top off at setting 18 where they are 960, at 21, they are 968, so very little gain and just more air for nothing. I think more can be had with higher reg pressures, but I don't see any reason to go beyond this without the 700mm barrel. All in all, I gained very little when it comes to numbers, but being able to utilize the higher pressures, with less spring tension and quieter shots, is worth it in my book. Sub 12 Airgunner had a great video about the bolt and seer polishing and he changed the angle of the seer so that you get rid of that gross crunch when you cock the gun, I copied his work and what a difference that made, 4x smoother. This Crown is, from what I can tell every bit as accurate as it's claimed to be, and this heavy liner does what it's supposed to do. It will shoot lighter slugs and pellets, in the 20 grain and up, but just like the Redwolf HP they will get erratic in a breeze because they're over stabilized with these twist rates. I have great confidence that the 1:24 STX barrel would be every bit as good as this one for 16 to 23 grain stuff. This heavy liner is what it is and should not be judged on what it can't do well because from what I see, this gun is a real winner. This kit originally was for the first crown and the gains to be had there are more substantial, but for the heavy liner, and the use of slugs that it's meant for, the ability to use the higher reg pressures for them is a solid gain in of itself. I stopped at 170bar and that's all the info I have to offer anyone who might be looking into this subject. I've read claims of 70 FPE out of the .22 crown, and I think they were said to be with the 600mm barrel. Now the Redwolf HP is a 65 FPE gun but it doesn't have a plenum and draws straight from the tank, and you get maybe, 2 mags before the board says low power, so those shots are from 250 bar down to 190 bar to achieve the claimed 65FPE out of the same 23-inch barrel length, before you are in need of a top off. With that said, this Crown is right in line with those figures in relation to bar pressure. So far, I am way more pleased with the accuracy of the crown, and the versatility of it as well. I'm not crazy about the barrel that's more like a break line but you can't argue with the results, it's easily my most accurate and versatile, as far as ammo option, higher power gun I have, I think it is more accurate than any air gun I have tried to date. That's a bold statement. So just to clarify, the 70 FPE claims were in a 600mm barrel in .25 cal. set up exactly how I have mine, So this is about all one can really expect out of this configuration.

I was also able to get it to shoot the 20.2, slugs and the 23 grain slugs, I just had to drop the speeds to 860, any higher than 880 and I think the twist is too much because I can shoot them well over 900 in my 1:18 barrel.
