Boiled Owl
Sharpshooter
Winchester make some bulk pack Xperts. The are copper plated 38 grain bullets simular to cci stingers. In my model 39a they group great. In a 10-22 they shoot shotgun patterns. IN the 10-22 target rem/peters standard VEL seem to be consistant. Rem/ely shot no better. The regular Eley stuff smell like burning plastic.
Be sure to clean barrel and shoot fouling shot in between groups when switching ammo as the lube can overshadow. The ruger seems to like the lead ullets and the 39a shoots the copper plated ones better.
We didn't clean between groups...oops!
