Not knowing your budget, I’ll repeat info I’ve reported before. Everglades ammo has a clearance on new primed 40 S&W, Nugent headstamp, manufactured by Jagemann. Primers are iffy. They report 10% failure to fire. I’m using them in plinking and new load development. They are 100% in my Beretta PX4 Storm, but my Springfield EMP doesn’t like them as well. I did fire off 100 rounds of them today. I was able to fire all 100 rounds, but about 15 took multiple strikes to set off. Nonetheless, I feel 1000 primed new cases for $99 to be well worth the potential pain, YMMV.
