Well here we go again> What is accuracy? We talkin about one inch at 25 yds with irons or optics at 50 or beyond that will produce groups 1/2" or better.Bolt gun or semi-auto? Rimfires are like fingerprints and women. Theyre all different and what floats one boat sinks most other, even from the samer breeder. Tried and true are CCI SV and SK Standard plus. Nothing supersonic will shoot accurately past 50 and most wont make it that far. I know ur BR 59 will shoot BLAH BLAH shells into a pin head at 100 yards. Ur full of the stuff that comes out our rear end. Ive seen The fellows with there mini mags shoot in ORPS or CRPS with that dumfounded look on their face and the " I cant understand it, they always worked awesome before" yeah at ranges 50 or under! Why do you think all accuracy records are held by subsonic ammo. Why are all Olympic Medals won with subsonic ammo. Hopefully smart enough to follow the trail laid in front of you. If not, dangerous things like firearms may not be ur forte!!!! Not trying to be nasty but enough threads about accuracy in 22 rimfires to form the link with subsonic and accuracy. Anybody who says HV rimfire ammo past 60 yards is accurate, well ive got a farmer down the road that's in need of ur service.
