What is the difference between the handi(.308) barrel,and the ultra(.308)barrel? I'm thinking about getting one. Also any idea who made the bullets for the .308 (7.62) full metal jacket military ammo? I was digging through some of my old army stuff the other day and found an M-60 ammo(linked) belt of 100 rounds full metal jacket. I pulled one of the bullets and it was a boat tail,and also sort of heavy but i don't have a scale to measure the grain.Later bull b 25-06
