Sorry, thread drift on my part, I was talking about 7.62 x 39 Wolf. Which also has a bad rap for accuracy but seems to shoot just fine through my 527.
I know a few guys that use the Wolf .22 for target pistol. I like CCI standard velocity in the blue label PLASTIC box. Others use Aguila and a few use the federal gold match which, if you ask me, is too pricey.
