I have run through thousands of rounds of their 45acp and 9mm. Also working my way through some of their 44mag and 45 Long Colt. So far, have only had a problem with 1 round - a 44mag. Primer was not fully seated and would not allow the cylinder in my super Blackhawk to rotate.
Otherwise excellent quality products at great prices. I buy most of my pistol caliber ammo from them.
