Alright so I took the plunge into the 300blk realm over the 4th of July. Bought a Radical Arms 8.5" upper and stuck in on one of my spare lowers (pistol build).
Bought a couple different factory loads, and some hand loads from TomKat at the Howard County show Saturday. First time out today I ran:
20x Nosler Varmageddon 110gr
20x 150gr FMJ TomKat loads (LC brass)
10x 125 gr TomKat loads (LC Brass)
Noticed a random primer on the bench and started looking at my brass and saw this:
Very odd growth on the Nosler brass. It obviously attempted to expand in the chamber but only on one side? Definitely very hot in my rifle as I had 3 blow the primers out of the brass and then had swipes on every other casing. No noticeable felt recoil difference though. In fact it was during cleanup that I even noticed the primer on the bench. Didn't notice the abnormal brass growth until I got home and started sorting the brass. None of the LC brass exhibited any overpressure signs.
Here are the blown primer brass shots:
Now my question is that the ammo is factory overruns from ShootersPro Shops, is it the chamber in my rifle or the loads themselves? I've got 10 boxes of this stuff (12.99/box over the 4th). Send it all back?
*edit here is the link to the ammo in question:
