The best repeatable, consistent 10 round groups have been 2+ MOA. Including several Noveske's. Dan Horner and the AMU had to use a 1/12 twisted barrel and 155gr bullets to make accuracy. Not saying they can't be reasonably accurate, but .5 MOA consistent groups is a pipe dream.
Form, can I ask please: Was the lighter 155 gr. bullet & 1/12 barrel combo still shooting subsonic?
Thx,
