Made the mistake of trying a 50-box Aquila 115 grain FMJ 9mm for last training session with a Gen 5 Glock 19. It was a dollar or two cheaper than the Blazer I usually buy. Had several failures to feed with the Aquila. It almost seemed as if the casings were too big to fit in the barrel. Was able to shoot the whole box, but had a lot of trouble doing so, so many FTFs.
I’m pretty limited on what I can buy locally. Atwoods Farm & Home is close by. For training, I get Blazer FMJ 9mm there, and Winchester whitebox when they have it. Have never had a problem with either of those.
For carry I’m running Federal Premium Law Enforcement 147 grain HST. I buy that at GT Distributors when I’m in Dallas. It’s a LE supply store, but sells to the public with most anything you’d ever want. Get whitebox and other training ammo, too, there when I can.
To get to Atwoods I drive right by WalMart. Swore them off years ago. Will never, ever, not ever do business with them again.
Academy is about 20 miles away. Used to buy there. But I swore them off, too, back when they got chicken and hid their ARs back in the store room after the Florida shooting. Told them so, too.
