poodle pumper, i'll take these one at a time...
I was always taught . . . "take care of your weapon and it will take care of you".
i've had probably close to 2,500 flawless rounds fired through this weapon. if it was broken beyond repair, it wouldn't bother me a bit to chunk it in the bar ditch and get another one. i'd be content that i got my money's worth out of it.
Why are you using that crappy looking ammo in your weapon ?????
those are handloads from new brass. when you shoot suppressed you will get blow back from the barrel. usually most noticeable 5 or 6 shells deep in the magazine, from my experience. sometimes in the heat of battle, you just have to stuff more ammo on top of them and keep going. i wipe them off when moving them to another mag, but they ain't as smooth as shiny brass. here is a 308 mag with new factory ammo.
I keep all my ammo wiped down with a very small amount of Break Free CLP.
why aren't you using vaseline?
Small ring looks to be from the reloading die. On some bullets that I use with a long ogive,they come out of the die with a small bright ring where the bullet stop spud is inside the seater die.--- pruhdlr
i have seating die marks on some of my bullets from new brass that had tighter mouths. if it was a seating die ring, it would be dirty like the rest of the rounds in the mag.
just occurred to me it doesn't make sense it would be from jamming into anything in the barrel. so... it must be from the cleaning rod i used to knock out the round!
