    I have been watching your videos for a long time and I know that you have changed springs in your 22lr to get a lighter trigger pull and on your cz it looks like you are using a Timney trigger and your pull weight looks like it’s 3to4oz. Can you share a little advice for someone else running the timney to get the weight down. Mine is about 8to10oz now and I’ve not messed with the factory settings just turned the pull weight screw almost out. I’m shooting benchrest and I’m about to order a Jard if I can’t get this pull weight down. I would appreciate any advice thanks.

    • @BROTUNED
      @BROTUNED 2 дня назад

    You can quickly determine the proper shim my using a small piece of plasitgage on the back of a cartridge. It saves time compared to taking everything apart and measuring with a depth micrometer or swapping out multiple shims. I have found that getting headspace as close to 0 without crushing the rim to offer the best results.

    @joewhite4081 21 день назад

    The sense behind the shims is to only take the slack out of your rifles bolt close you don't want it to stiff you don't want to sloppy that would be the reason the first shim worked well for your rifle a heavily worn rifle would really prefer the thicker shims

    Rewatched this as I hadn't shot this in my current match rifle till recently. I have mentioned previously that I sort my rimfire match ammo and found that this stuff was the most consisten of all the quality types when it come to weight overall length and rim thickness. This was also super consisten over the chrono with the best SD I've seen for myself. Didn't shoot out of my rifle as well as some of the Lapua my rifle likes but shot as will as R50 at half the price so was impressed.

    I found this channel because I was wondering the same thing about air rifle porting. I've tried many different things including making my own shorter piston in aluminum Tubing. Got in a few over 700 FPS, and with less recoil. But it needs to be stronger. Might need to have it made in TITANIUM Yesterday I put my stock piston with only the hole plugged back in. Original seal, but lubed with 20,000 weight diff lube available at my local hobby shop for 12 BUCKS. Plus you get a lot more than crosman sells you for 20. 600 FPS with one virtually free change in assembly. I thought the thicker lube might slow the piston, but he results are repeatable. Crosman lube takes me back below 500 FPS.

      That’s awesome I like mine around 600 fps the best the recoil isn’t to hash and it’s still accurate. That’s super cool you made an aluminum piston and if you do the titanium one I’d love to hear the results. Cheers man and happy modding

      @@BROTUNED I have another practically identical rifle to the one I changed the lube in. Only difference is I've shortened the stock piston which is giving me virtually identical muzzle velocities to the unit with the new lube. So, naturally I'll be switching up the lube in that one to see if I get even better results, you know, For Science. Need more data. The Crosman 0.177 Pointed, 7.4 grain seem to give me the most consistent velocities within +/- 5 fps. Everything matters when it comes to accuracy.
