>223/5.56NATO What Happened?

[loose noose]

Excellent advice there Gunny, my son and I went shooting the 5.56 and 7.62X39 both Rugers (Mini-14 and a Mini-30) yesterday morning, we recovered all the brass, from twice fired casings and carefully placed them on my reloading bench, when we were done, to be carefully inspected prior to reloading, I generally discard any casings that have been shot at least 5 times anyway. The Mini-14 is of the 186 Series however has gone thru about 4-5000 rounds of ammo, however the NATO Maximum gauge still will not let the bolt go forward, nor will the .223 Field gauge. I recently replaced the scopes on both rifles with a Weaver K-4 on the Mini-14, and a "Target Sport Tactical" (Unknown brand piece of junk) on the Mini-30, which has recently been purchased new. While sighting in both rifles the Weaver K-4 gave the best results, although the Target Sport did ok on the windage, however the elevation would not move up or down. I have no idea where I even got that 4X scope, but it is junk, even though it has a range finder incorporated on it or so it says. Any way after placing the steel ringers out to 100 yards and with the wind blowing at 25-30MPH we commenced firing, once we figured out the cheap scope we started hitting the 10" plates quite regularly. However this should be in a different sector, but it was all shot with reloaded ammo. Needless to say I removed the scope from the Mini-30 shortly after getting home. Even in the high wind, that kept changing direction we were able to hit the plates 100% of the time using those reloads.

I wish I could remember where I put it so I could share but I had a Winchester .308 case show sign of case head separation after just firing the factory load out of my AR10. The line was so fine it took just the right angle of light sprinkled with a dash of dumb luck to catch it.

So I agree with the commenter that said sometimes you just get a bad one.

Had that happen with a Brownong M2 50 cal years ago.

Bet that was fun. I had a neck separate in my AR pistol this summer, factory brass even, I couldn't get it out with the Brownell's tool, and I don't have reamers, so I had to pay another gunsmith to fix it.
