Who here is familiar with a Military Sniper Round

from the Vietnam Era that is identical to the .300 Win Mag A.I., but almost 1/8" longer from the belt to the shoulder.?.? The head is also stamped with a backwards 300 to the left of REM-UMC. Anyone here know what this cartridge is??? The only other differences I notice are a longer neck and I'm not 100% certain that the taper is completely blown out like the .300 AI. Thanks!

300 AMU, Army Marksmanship Unit, and it was a target round, not a combat round.
Thanks...did this use something like a 172 or 178 grain bullet? I think that's what the fella who gave me the brass thought he weighed them at. I would not be surprised if they were getting 3400+ fps...
.300 AMU
The bullet in the .300 Improved AMU has a hollow point. The dimensions of the case are:
bullet - .308"
neck - ..335"
shoulder - .485"
base (above the belt) - .507"
base (at the belt) - .525"
rim - .523
case length - 2.770"
overall length - 3.741"
Best.
