UPDATE: Group photos and S.O.S on disco/carbine hunter…
…I can’t say if it was the actual lighter valve spring or the valve itself, as I did not deduce as I should have by keeping the disco valve in place but using the “boss valve face” with lighter spring. Instead I just opted to put the “boss valve” in and be done with it. I am convinced, through my limited, but accelerated experience with these 22xx’s…that the “Boss valve” would edge the “disco valve” by a considerable margin, and I’m sure most of you would agree with that.
On Max hammer spring compression on my power adjuster I nailed a string of 18 good shots with a low of 730 and a high of 760 fps with 25.4 gr JSB KINGS. Accuracy testing will commence when I find some time.
This is what this baby has in her:
Disco tube, Crosman trigger frame, TKO trigger spring kit, Mountain air trigger shoe, .25 LW 24″ barrel blued and accurized by Mountain air, Crosman steel breech, MA .25 brass bolt probe, HDD (otherwise she will degass with one or two trigger pulls 😛 , Muzzle mack power adjuster and Stock adapter, M4 six position stock, 60 gram polished Crosman hammer and heavier gauge hammer spring (sorry, not sure what it is from…) MA muzzle brake modified by me to clear fill cap, Scot (GTBJ) custom made condor foregrip, modified by me to fit this project (trunk liner and rustoleum olive drab paint applied by me), 3×9 nikon prostaff with digi tape treatment, Mac 1 one piece drooper, wally world flavor of the month bipod.
She is light, she shoulders well, she hits hard enough for small game, and I am confident she will be accurate to boot!
Here she is:
