What shorter COAL? You're considerably longer than the bullet manufacturer calls for, and just .002" under the SAAMI maximum COAL for .380 ACP.
Aguila, I was referring to the fact that I used Jacked bullet data for a plated bullet. I didn't have any powders on hand that were listed in my load data for plated. The Min COAL (as Lee Manual States it) was. .980 for Jacketed bullets with Universal powder. It did not occur to me to use the .960 COAL that Lee stated for the plated bullets with other powders. Lee lists a min OAL not an average or a maximum. So, I assumed that going deeper could create over pressure. I decided to experiment with this load erring on the side of caution. After reading the responses here, I went back to the press and re-seated them down to .960 then went to the range. I did not re-crimp only pushed them in .022. Best 380 rounds I ever shot.

I didn't even try chambering in my guns the rounds that failed the chamber checker. I'm very new to reloading (less than 500 rounds under my belt) so I'm being very cautious.

The case lengths checked out ok.

Thy Lyman M die should be here in a week or two. I'll return and post results here.

Shooting for 100% success rate (pun intended) like I get with 38 and 357.
