My DPMS 5.56 is what I bought the Wolf Ammo for and it is 1x9 twist. My LR-308 is 1x10 twist. Well, I hope the 55gr wolf ammo will not rough it up. I have not found any cheap .308 wolf ammo. I am currently waiting on some more surplus ammo for my .308. I forget the name it is I think Czech Brass Surplus ammo. I ordered some Lithuanian at .65/round, which is way to much for plinking. But at least I can do a litlte shooting with it. The Czech stuff I am hearing about will be around .45-.50 a round. It is your typical east european brass cased surplus ammo I guess. Anybody had any experience with that? I don't plan on doing as much shooting with my .308 as with my 5.56.
