Case Stretch

[Steveu]

Don, I checked the starline 45-70 brass after I formed it and it measured.010, it I did not check it all the way around. I will check it again and see. I prefer to inside ream also. My fired neck id is .412”, bullets patch to.4105”.

Arnie, those are patched with SC55W which shrinks .0005” when patched wet. I do have some WW brass I can use to see if it works. I’ll be shooting a gong match tomorrow to test them out. It is a short range due to the high winds forecast.

What I can’t figure out is why no issues with the GG bullets.
