There was ONE loudmouth over at TOS a few years ago, who mixed in some rounds of GA Arms Canned Heat, with some of "
Uncle Dub's reloads,"

and blew up a crappy, out-of-spec Bushmaster, with SOMETHING that came out of said container of mixed ammo. He complained bitterly & loudly across a
LOT of boards actually, about GA Arms, who not only analyzed ALL the ammo he sent him (they determined it was one of "
Dub's reloads" that was the culprit), but REPLACED his rifle at
their cost
anyways, and the loudmouth CONTINUES to complain to this day.
I've sent 2k of Canned Heat .223 downrange since '07, and I'm sitting on 2k more for practice. Never a hiccup - never a problem. If you have some you don't want though, feel free to ship it to me for proper disposal! I'll even spring for the UPS man to bring it!
