Rimfire firearms have a mind of their own, when it comes to ammo. Most of the time, the accuracy goes up with better quality control. Better quality control costs more, and as a result so does the ammunition. A couple of my rifles shot sub-moa with Federal 900B, but they quit making it. Eley EPS black box shot excellent in several of my match rifles, but couldn't afford it any more. Currently Wolf MT shoots better in the majority of my rifles than anything else for the same money.
Find what yer rifle likes, and buy as much of it as you can afford.
