Re: New gun advice...
7mm-08 is a pretty sweet caliber too.
6.5-284 is what I am shooting for a LR rifle and I love it. I do reload however.
Another option is the 260.
If I were in your shoes and wanted over the counter ammo and LR high BC bullets, I would go 260 in Savage. My buddy has one and is pushing a 140 Berger at 2850-2880 with a 26" barrel. My 6.5-284 pushes a 140 Berger at 2970 in a 24".
I am kind of in a love affair with the 6.5 bullets right now for some reason.
