Just picked up a box of TulAmmo 150 gr in .308 Win. At $9 a box in WalMart I couldn't pass on it. I was going to use it for plinking with my Rem 700 SPS Tac AAC-SD (1:10 twist). Then I read some stuff online about it messing up your barrel??? :huh: Anyone shoot this stuff out of a .308? Any problems? Results? Thanks.
