Re: Walther P22
mine is real finnicky with ammo but it is an accurate shooter, very accurate for that short of barrel/sight radius. I've not had issues with it like you're having though. Do you bore-snake at the range at all? I snake mine periodically when I'm shooting it, might be just enough to make the difference. I only actually 'clean' it once a year maybe!
Remington 36gn hyper velocity (copper plated) work best in mine (for cycling anyway, not accuracy). But even with all lead, I've not had degraded accuracy. wierd.
