YES!

Works pretty good in mine. Mine is a TNW 7.62x51 variant.
I've run about 1000 rounds through it, and only ONE jam/stoppage. The rim of one got stuck in the bolt, and wouldn't slide down far enough to load into the chamber. So the gun got stuck locked 'open'. I eneded up having to use a screwdriver to pound the round down through the bottom of the bolt (out the bottom of the gun). Slot screwdriver on case head, and just 'hammered' it down with my other hand. I'm guessing the rim was too thick (out of spec), as every other round of the PRC 7.62 slides down the bolt easily. Ran like a top before and after that incident. No damage to the gun.
I run it a +3 clicks and seems to run pretty smooth. Fired cases look fine.
I have 6 cases of the stuff, so plan on using it for a while.
