Ok so I've got my .308 built and am getting ready to sight it in! I have already purchased some Winchester Super X 180gr Power Point bullets. My question is "what kind of factory ammo do I need or will these do?" I wasn't thinking when I bought these but plan to use them to just break in the barrel. The gun will mostly be used on deer and targets at 100-600yds. Also if possible I don't want to break the bank with this ammo, but it will have to do until I can start reloading thanks!
