Your target above says "after accurizing". Can you let us know what you had done to it and how it was before this work?
Thanks!
Sure thing. As new, three cylinder throats measured 0.359” and three measured 0.360”. I enlarged 3 so they are all 0.360” now. I only shot two 6 round groups before with the same ammunition shot after so not a lot of data. But after groups were about an inch smaller with that same ammunition.
