I guess I should explain my situation before asking my question. I have a Savage Striker .243 that I want to switch to a .308. I have not seen a striker barrel floating around anywhere, but there are plenty of new and used .308 rifle barrels. Generaly, everyone claims there used .308 barrel has a low round count, but you never know that for sure. My question is, since the barrel is going to be cut down 6-8" and crowned, does the round count of the barrel really matter? Thanks for your input.
