Has anyone tried these and had success? I've tried these in my Krait L .177 which is shooting V3 10.03gr KO slugs at 960fps and my U2 600mm .177 which is shooting 16.5gr at 885avg and neither barrel likes these slugs. I've gone as far as removing excess lead flakes via fiber cloth and with both barrels they shoot 6-12" groups out to 35yds.
, at 25, 40, 62yds. Made no sense! I checked my poi at 25yds and 62yds and it was fine, but when it came to killing it wasn't. Finally figured out that's it's just inaccurate as hell. Sad, they're are priced at $8 for 400ct!
