Panthera 22 700mm polished 1:16 bbl front bottle impulse air 1350 otherwise a stock gun. Have only shot 36-40gr. Pretty much tested all brands. Settled on Javelin 217 40 maxed out (1000+ fps). Ive shot sub-moa up to 175yds. Repeatability Id say a tad higher than 7/10 - prob near 9/10. I will say...
ive got the 380 30 with hades running 830fps - its quiet enough for me with three baffles on the 1350 impulse air. The 380 can get real loud real fast so start slow and work it out for yourself with whatever mod you got.
