Investor beware _
I know AA makes some primo ammo that many competitive shooters use. But my personal experience was a purchase of 500 rnds (not from AmmoKate) but anyways I had close to two dozen rounds that were really damaged with severely dented casings, from something other than a typical deflector dent, so I didn't fire them for safety sake, also visibly cracked necks around the 'new' bullet seats on several rounds, like what you get from too many reloads when the brass is brittle. This prompted me to visually inspect every single round before I shot them and I probably discarded 30 or so. I mean I could have shot them I guess, but I'm not that desperate to experience a blown out round or separated case.
Also when I started reloading them I was getting cracked case necks on many of the hand loads, and no I don't have an annealer but could have used one. Also after reloading 150 or so rounds with new .223 the mouths were failing to reform to original size, it was so bad that many of the bullets were falling through into the case because the brass wouldn't hold it's shape anymore, even with a mild crimp. I really have to wonder just how rounds were through these AA Re-mans ???
I wouldn't have been so P.O'd about the ammo and a few too many defects, except the Seller was advertising and selling as New $$$ (and Re-man was not at all in the description). After I phoned them, and AA to express my concern the website was updated like within an hour.
After that one experience with AA, I'll buy Federal or whatever instead. But to each their own of course. - that's just my one experience.
