BTW - You need a effen 10 rod surveyor's tape to measure MY eccentricity!!
I'm not gonna run with any ball micrometer jokes, but it's a little hard to keep a straight face when you use those two words together...

After much research, I found the problem was occurring with 9mm CBC brass. Sorted that brass out, no more problem. I still don't know why the CBC brass fails, have yet to figure it out.

Are you sure it's not the length? My Sierra manual, edition V, recommends a COL of .930 for their 90 gr JHP bullet in a .380.
