RE: Two barrels for H&R Ultra
The 7x57 and 7mm-08 are pretty close ballistically , with the7-08 accually having a little advantage in velocity.The pressures are also a little higher in the 7-08.So unless you just want that 7mm performance in a short action cartridge you might think about a .308 which would give you a 30 cal. in a more modest velocity range than the 300 weatherby.Just my two pennies.
