Looking to save some time for a friend who has a T-3 Stainless Syn. in the 300 Win. who wants to shoot 150 grain bullets on a western hunt this fall. I showed him yesterday what the 200's shoot like under...1/2 moa. Still wants the 150's loaded. Anyone have one of these rifles in this caliber and loaded the 150's? I'm really impressed how well this rifle broke-in and shot and cleans up like a custom barrel. US manufactures should take heed.
