Update: I measured the the casings for the factory and the brass I was using along with some brand new brass. All measured roughly the same (just under the max length). I primed some brass (old and brand new) and neither would ignite the primer. I had some factory brass that was primed but not loaded. Oddly, that worked perfectly. The primer depth might be a difference, but they look similar. The Primer itself in the factory loaded looked flatter and went all the way to the edge of the primer pocket, while the primers I used rounded down at the edge. I tried CCI and Winchester rifle primers and the Hornady primer on the press and a hand primer. No primer I load will ignite. So, I seem to have eliminated brass length and anything past the primer. Anyone have an idea? I'll try to get some pictures tomorrow. Thanks for any suggestions for things to try.

I just started reloading and one of my reloads is 30 Carbine. Factory rounds work fine (firing every time), but my reloads all get light primer strikes. I'm using Winchester rifle primers (non-magnum). I assume factory reloads use rifle or thicker USGI primers, so I doubt it is primer or firing pin springs (as the harder factory primers should fail if it were primer thickness or firing pin spring). I am thinking it is head spacing/case length problem, but I am trimming to book spec. Anyone have any suggestions or similar problems?

I had some damage to the extractor on one pistol, but I was lucky it wasn't worse. Given the name of the company, I would assume they were from Texas, but that is just a name.

Here is a picture of the ammo I still have. From left, Case that blew out the entire rim (fished from my PCC), Bad round, case from bad round, and on the right is a Browning factory shell for comparison.

I'm still here. I bought 1000 rounds and i checked and could find no sign of the reloader (This was from about 2010 time frame). All ammo is stored in a cool, dry place with desiccant packets. This were bulk packed in a cardboard box, 500 to a box. I originally thought it was another problem because of the oddity of the failures. I checked the brass and didn't notice any Glock bulge, but it is possible that the bottom of the case was reworked and stretched one too many times. I'm looking through my stuff to see if I kept one of the blown out cases. And as soon as I identified the problem, I started pulling them apart. I just want to try to isolate the problem so I don't make the same mistake.

A long while ago I purchased some 9mm, 115Gr FMJ ammo from what seemed to be a large scale reloader. They had a nice booth and lots of complete ammo for a decent price. Forward a dozen years and that ammo finally came up in my quasi first in-first out ammo rotation. I found that 1 in every 15 rounds had a detonation, blowing out the back of the case. I had it happen in 4 different guns before I figured out it was the ammo. I tried to identify if there were any way to isolate the bad rounds and couldn't find any external signs (like cracks or damaged cases). Just recently I got an ammo puller and expected to find some rounds with a double charge of powder, but could find anything obvious. So, does anyone have any ideas of the cause, so I don't repeat it? The Brass failed at the base of the brass right above the rim. Several completely separated the base (rim), but most had a small hole blow out. None showed any blow out through the primer. Overall length was the same (so no squashed bullet over pressure). No visible signs of damaged brass. Powder that I pulled from the opened bullets varied from about 4.5 Grain to 5.2 grains. I don't know what powder that was used and I tried to weight the charges that were left in the bullet puller hammer, so there may be some variation there. 5.2 grains doesn't seem like an over pressure volume unless it was a very fast powder and then it doesn't seem excessive, but someone else might have more experience. I didn't see any case bulging or primer bulging, just the hole. Could the cases have been reloaded one too many times or was there a over pressure from too much fast powder?

Anything still available from the Automag 3?
