I was shooting my Para Ordnance CCO in 45 Gap today and had some interesting ammo failues.

I was shooting Federal American Eagle 230 Grain 45 Gap ammo. Every so often (5 times in fact) I had what seemed like a wierd "bang", not thecool type that indicates the gun has discharged, and I felt like hot powder hit my face and to top it all off smoe as comming out of the gun (behind the slide for example). I thought perhaps it was a squib and prompty dissassembled the gun but there was no round lodged in the barrel). I thought wel mabe it was just a fluke but after 150 rounds and a few failures to feed Ithought it must habe been the ammo. I tried Remington 230 Grain JHP and had no problems, I also tried Speer 230 grain and had no troubles. After shooting and being satisfied that it was indeed the ammo and not the gun I went loking for some spent shells (I know I should have done that in the first place) and found this:

The left shell is of the ones that had the problem. Anyone have any ideas as to the cause?


I will also admit I had some Failure to feed issues but I attribute this to my limp wristing (I know big bore semi-autos need locked wrists to shoot reliably).:o

Pierced primer. If it was a reload I'd say you put too much powder in it. From the factory I'd say they messed up and overcharged or bought a bad run of primers. Send them to Federal with an explanation and they may send you a coupon for a replacement box of ammo.

Have a look at your firing pin. If it was cut by the escaping gas the end may need to be smoothed up to reduce piercing more primers. I'm not sure why you would have the firing pin wipe on the two that didn't pierce, but not the one that did.
