Consider your cartridge options from the ballistics stand-point before you decide which cartridge you want in a barrel that's significantly shorter than a typical rifle barrel.
Cartridges that depend heavily on the
velocity of a light, small-diameter bullet for their effectiveness on game also depend heavily on
barrel length to develop their velocities.
Shorter barrels favor cartridges that depend more heavily on
bullet diameter and weight and less on velocity.
In a 15- to 20-inch barrel, I'd look first for something like a .45-70, .444 Marlin, .405 Winchester, or .358 Winchester long before I'd consider a smaller-caliber cartridge.
If I were determined to have a .270, I'd make sure to give it enough barrel length to do it justice � ideally not less than 24 inches, not less than 22 inches in a compromise.
Whatever the cartridge, I'd get the barrel from
Bullberry, not from T/C or (shudder!) Virgin Valley.
