Factory ammo blowing out primers?

RT2506,

You see it more frequently is bulk 5.56 ammo than anything else IME. You know its hot when you are blowing staked primers out. Nothing like the clinch factor that happens with your mag explodes out the bottom of your AR and you get some brass frags in your face. You unclench once your done confirming a 10 count on digits.

I cleaned up the action & installed the new Shilen barrel & now it shoots lights out, When our dealer did call Savage they said they had some bad barrels that were rough & causing excessive copper buildup quickly & shedding jackets on the way out.

nice they admitted issues. Glad it all worked out with a nice accurate setup in the end.
