I had my first squid out of 30k rounds last month. I had left my Ammo can open when it started raining as I was cleaning up, the next time at the range I was having a ton (5%) of primers that wouldn’t fire (147gr bear creek moly 3.0 gr TG win primers). Sure enough I had one primer that barely touched off and left the Bullet in the bore. Luckily I was just training at the range. The funny thing was that I don’t think my ammo got that wet, there was no water in the bottom of my Ammo can. But obviously it was enough to cause issues.
