Hey guys, I've never owned a bolt action or a scope. I jus purchased a Hog hunter in .308 as a base for a rifle build I've been looking at several scopes:

Primary arms 4-14x44 ACSS
Nikon p-308 4-12x40
redfield revolution 4-12x40
vortex diamondback 4-12x40 AO
vortex 3-12x56 AO hog hunter

Are any of these good choices? I'd like to stay under $300. I hear good things about the primary arms but that sucker is HEAVY.
As far as application I don't plan on shooting past 500 yards. Typically I'd like to shoot as best groups as possible at 300-400yds on paper.

I'm planing on getting a nice Boyds stock as well for this and setting it up as a prone, bench, target shooting rig/ range toy. I'm not a hunter.

Thanks for the input!
