Having tried many handloads in several .222s, it seems that 50 grain bullets are generally more accurate than 55 grain bullets. My current favorite load is the 50 grain Sierra Blitz (#1340)and 20 grains Reloder 7. Not top velocity, around 3,050, but very good accuracy. I normally use CCI small rifle primers, but the Fed. 205 Match and the Rem. SR BR work about as well.

From an accuracy standpoint, the 50 Blitz is the single best .22 varmint bullet I've found. I use it in all my other .22s as well, including the .223, .22-250, and the Swift.
