Y'all do realize that that the 300 PRC, 30SM, 300WM, 300WSM and many others shoot 308 bullets right? I could be mistaken but the OP didn't specify 308 Win rifle, nor do I think thats what was intended.Agreed...a .308 trying to shoot 245 seems to me to be alot like a fellow using a MANHOLE cover in a Frisbee contest! Just me!
