Both will fit the requirement. Agree 100% the .303 is a proven all around take it down round, not a pretty firearm. No need to be concerned about dragging it thru the woods or getting 'use marks'. The .270 shoots flat and has excellent ballistics with moderate bullet weight.

I used a 30.06 for many years (model 70 win.), recently started shooting a .243 Ruger m77 (used purchase I might ad) that is consistent shooting 1" groups at 100 meters.

Never considered a .303 until a buddy told be the story of his Dad dropping a moose with a surplus one while guiding a group using 'latest and greatest magnum rifles' that could not hit it standing broadside. I would get a .303 carbine if I could find a good one!

As always, user choice............
