Sell what he has and get a new 300WM, then.@memtb I think 338WM is a bit more than needed. He already has an old Winchester 670 in 300WM. It shoots OK, but he's looking for something a little more modern, and is excited about just "getting a new rifle".
Two words...Carlos Hathcock. Honestly my only guess is in order to utilize high BC long range bullets the 06 can propel at a higher velocity. A 308 with a 200 grain slug is gonna be 2450 fps and require a little more dial up. Might be better off with a 155 Scenar or 168 Berger and let er rip. It can be done.OK so I'll be the noob here...why is .30-06 recommended clearly over .308? I truly don't know and not causing a beef. Is it that much better at long range?
