Ahh, you guys are great!!!! I'm somewhat new(3 years but non-military)) to shooting, I just didn't want to tell him he was full of shit about the "one rifling groove" in the barrels of his rifle when he was in service, without having served, and being new to shooting. It just seemed to be really against everything I have learned these past three years about firearms, that's why I asked. I just wanted to make sure he was out in left field. The bouncing bullet around in the barrel was just dumb. But he was telling me how ALL military barrels only had ONE groove. He swears by it. It's not like he's doing a false valor thing, I know he was in service(82nd Airborn, he says), he has pictures of himself in Kuwait with desert shots and other service guys there too. Where do these guys get this weirdness from?
