Re: Which rifle
Both are excellent calibers for what you are wanting to do with them.....with the exception of the hogs...b/c they're pretty tough little SOB's!
I would use one for deer, and have one for hogs/large game.
For deer I would recommend the .257 Wby...only because it's a little flatter shooting caliber.
Both calibers (.25-06 & .257 Wby), shooting a 115gr. projectile @ 500 yards would be devastating to a deer!
However I checked a professional ballistics table...and if both calibers were side-by-side shooting @ 500 yards, both using a 115gr. bullet.....
The .25-06 would be shooting @ 51.4" low.
The .257 Wby would be shooting @ 35.2" low!!!
The .257 Wby is gonna be a flatter-shooting bullet...and since it has a flatter trajectory, it will hold more energy when it impacts!
I personally shoot the Weatherby (brand) 110gr. AccuBond loads for whitetail, here in Alabama...A guy I know who OWNS an outdoors store (so he pretty-much has his pick of ANY guns out there)...hunts everything from Whitties to ELK with a custom-built Dakota rifle ($ 6,000 gun ) in .257 Weatherby!
So, I took his suggestion, and tried it...and I LOVE it!
It has become one of my favorite calibers of all-time...and I don't think I'd trade it for anything!
