TST....a few years ago while I was on the take from uncle sugar, I did a favor for the local SEALs and EOD guys. Nothing strange, I just gave them/their wifes a free CCW class. We did some shooting with all their cool stuff after they finished qualifiying. They asked what they could do for me. I really wasn't looking for anything, other than some range time with the .50s, etc.
One day I got a call telling me to look in the back of my truck. I did. In the back was a case of .300WM ammo, lots of brass, a couple boxes of .50 ammo and lotsa brass. BUT...one of the ammo cans was full of .50 APIT. I can't, or wont, run that through my .50 as it is a bit corrosive.
