Bought 100 rd. trial lot of 55 gr. FMJ, brass cased, boxer primed ammo in the mint-green boxes. I was hoping the stuff would be reloadable.
Holy crap, out of just 40 rds. fired (2 boxes)yesterday, I had two blown primers (1 each box)! And I just noticed today that there's at least one split neck in those shells! This is supposed to be brand new, factory loaded ammo!
In addition to the blown primers, I noticed that several of the other cases had the dark smudge around the primer from gas leakage. And get this: one of the cases that blew a primer had the most severe looking case head seperation line I've ever dreamed of. I can actually feel it from the outside. I'm glad it didn't rupture totally in my bushmaster.
Most of the rounds chronied at approx 3100 F.P.S., and sound/recoil seemed normal. The two cases that blew the primers also had brass extrusion into the extractor groove.
What's up with this crappy ammo? Are they trying to kill us? I bought this stuff with the hopes of reloading it and it's not even suitable for first-time factory fire! I've got 60 rounds left and I don't think I even want to touch them.
Should I be concerned about my rifle? It seemed to be shooting fine after words. It jamed just twice when there was a loose primer floating around in the action. Is there any damage I should look for at the bolt/carrier to make sure my rifle is safe?
Thanks,
junior
