9mm case length and OAL

[email protected] · April 21, 2006, 10:53 PM

i was reloading 9mm, but since i did not trim all the 9mm cases to the same length, the OAL is betweeen 1.160-1.169 out of the 400rds, is there a big difference in performance of the bullets associated with the OAL and how deep the bullet is seated. please give suggestions.

There is no relationship between case length and OAL. Your .010" variance is due to case wall tension and bullet nose profile difference.
