Dip$hit me got a terminal case of the dumbs on Wednesday.
MARK YOUR MAGS PEOPLE!
ONLY 1 CALIBER ON THE BENCH AT A TIME!
Luckily, the only thing that was destroyed was my rifle, not me. Overpressure exited through the mag & shot the baseplate a quarter inch into the bench. A half second of inattention was all it took.
Don't be me.
Pay attention.
