PMC XTAC 55gr blew my rifle up. Was out shooting under night vision in the Santiam forest let my buddy shoot my rifle and he noticed that the last round felt way more powerful then the others. Looked down and the gun had blown the mag out of the rifle and blew apart the upper. Was a Geissele bcg and bolt criterion 13.9 and a super 42 spring with an h1. Brass pulled from chamber was 5.56 and ripped at the base. barrel had no obstructions and the bore looked clear. Gun was properly head spaced and passed go no go when built. Lot number of ammo included in photos. Prior to this range trip I noticed a load that was hotter then the others from the same lot that required a mortaring to remove the case but seemed fine otherwise.
