I've had good luck with Blazer and Magtech of the big names out there. I've reloaded for so long though that I don't buy much pistol ammo off the shelf. I ran several boxes of factory .380 once I got the G42 and the worst was Winchester. A match I attended in October of this year saw Blazer and Federal 9mm fall below match power factor of bullet weight times velocity to get it over 125,000 (124 grain bullet going about 950 FP's for example)
i think it is a bit hot or miss with some ammo since people are still buying it by the gross to stock up. Seems like the quality has been sacrificed for quantity.
Thanks for the info! We usually buy Blazer or Winchester. I think you're right on the hit or miss. Also, it seems to depend on the weapon. My Bodyguard was very picky (to the point I traded it in for something else) with certain ammo, but yet that same ammo would run like better in my Sig.
