most 22rf rifles shoot best with "standard velocity" ammunition. There are to many reasons to go into this here, so I won't. While training junior shooters, with many different rifles and models, there was only the very odd rifle that would shoot extreme velocity ammunition well. Some of the semi auto rifles wouldn't function with standard velocity ammo when they were dirty, but they did shoot better.
I know, it's more of a kick to blast away with super vel ammo but, if you're interested in tiny groups, either match grade or standard grade are best overall.
Six bucks a box, try purchasing some "Gold Medal Match", it will put a knot in your shorts.
