A strange thing happened while developing some 380 loads ...

I had the similar issue with some 45 ACP loads. Case walls were thicker on some. There was not really a noticeable bulge, but it changed the OD enough that they would not readily chamber in one of my 45s
I know this is a .380 post. What brand? I have been shooting and reloading 45acp since the 80's and never measured one that was different. A merc is trash but I am quick on a problem with the brass I target shoot with and no problems. I shoot at least twice a week on the average. Just trying to find out if this is newer brass. Mine are older. I have one 45 that has a tighter chamber and likes .3515 lead better but is not a brass thickness problem. Just asking as I like to be in the know.

Bullets were Berry plated lead round nose ....the cases that were thicker are MAXXTECH.

Unpacked several boxes to find these reloads.

I have never seen that brand. Thanks for the heads up.xxxx I just looked it up and people are saying the volume is different and don't reload it as the pressure will be different. The brass being thicker would downsize the bullet and not be as accurate. Lands in a 45acp are pretty thin. :eek:

I'll go out on a limb and guess he meant "Magtech".
 
Had a similar issue a few months back with .45ACP and it turned out to be a case length issue. There was once a time when I sorted my brass carefully as to where it came from (mine or range) and how many times it had been loaded, etc. Those times are past and as a result, I learned eventually even relatively low pressure pistol brass will stretch.

I loathe trimming brass to length as my least favorite reloading chore but it made a big difference in some of my .45ACP handloads performance. I've also begun to sort brass by manufacturer (again) and that's helped some but not as much as trimming to length. The lesson was every so often it pays to trim pistol brass and not just the higher pressure stuff.

Good luck with your uniformity issue - hope it's the bullet seating as that's easier and faster to fix.
