RE: .257 Weatherby Magnum
I have a Mark V Sporter in .257 Wby Mag that shoots great groups with some cheap Remington Ammo that I bought from Cheaperthandirt.com for $15/box. It shoots sub 1" groups without any difficulty and I have killed two very nice bucks in Kansas with it the last couple of years. That's with a Simmons scope and I haven't done a thing to the gun.
