Notice how a primer has popped out of this round.

There are some examples of what we found inside the mags.

Next, to give equal time, we shot a Mini-14 mag loaded with 5.56 rounds.

I shot it with the AK.

I caught this pic to the next mag, immediately after the shot, as it lay on the ground.

You can see smoke from the rounds cooking off.

Tman shot it with a 5.56 and this is the damage to the exit on the mag and the backer board.
