I recently purchased some WST to load 45 ACP. Hodgdon specs for a 230 grain flat point show 1.2 inches as a COL. I thought I would check fit the 1.2 inch rounds I had loaded in the barrel of my SA Micro Compact and my S&W 1911. I found they were very close to flush in both barrels. I then wondered how my W231 rounds that had a COL of 1.265 would check out. The 1.265 rounds were "out too far". My question is, if the round headspaces on the casemouth, how can the COL affect how deep the bullet is seated?
