Hi All,
I have an Impact in .22 and I decided to try it out with the entire shroud removed. This gun has never performed as well as my Bobcat.
The results were quite disturbing as the accuracy went out the window! I have been trying to get this gun to shoot as well as my mk1 Bobcat, 20mm at 50 meters, and haven't been able to do so even at 25 meters.
I have been doubtful of the extending shroud, it has loads of play in the extended and retracted form, while I have been able to address this with well placed scotch tape I decided to see what effect a bare barrel would have.
I shot my worst group ever, I print out 144 18mm circles with 2mm bulls on an A4 sheet and shoot from 250 to about 140 bar, 126 shots, gun is shooting Jsb 18 grains at 863 fps reg is at 125 bar.
I expected the gun to at least touch the 2mm ring every time at 25m, like the Bobcat, but had many shots completely miss the 18 mm ring. My shooting skills are OK, I shoot at least 60 rounds daily since April last year and 120 rounds since the arrival of the impact six months ago
Anyone experienced issues like this before?
I have no idea what to think as it seems as though I may have a very good looking but inaccurate premium airgun.
I have tried:
washed pellets, washed and lubed, lubed, straight from tin, more speed, less speed, changed All exposed orings, set screw is always in place, clean barrel, fouled, have adjustable scope rings, have optically centered the scope, chronied a full string of 126 shots with an ES of about 10 fps, inspected crown, inspected grooves and lands inside and outside under the crown protector, pushed pellets through barrel and inspected, have put over 10000 rounds through the gun, have gone through the troubleshooting guide.
I am going to try a different scope and see if the current scope is not holding a zero, the dispersion is mostly horizontal. Current scope is a hawke 8-32x56.
I really have read just about everything impact related, and am open to any more reading suggestions or ideas. Trying to avoid returning this gun as I love the whole concept, I have even considered taking the Bobcat barrel and fitting it in the impact, but the Bobcat was bought second hand and is out of warranty and shoots too well to mess with.
