Ok, please save the comments about 22 Mag ammo not being a real defensive round. Anyway, I read another post recently about bad primers in someone's 351c snubbie. Super x ammo apparently purchased from Walmart FWIW. Same thing happened to me this weekend, Super X ammo from Walmart. In my box of 50, about 5 refused to fire until the second strike. First strike made a decent dent in the cartridge, but nothing happened. I was shooting an NAA mini PUG. All my CCI ammo was perfect. Anyone else with Super x 22 mag ammo issues?
