    A Weatherby MKV with a 24" barrel (26" but with a 2" brake) is long enough for the big 460?

    I think we'd need the full load recipe to calculate burn rate and find out if the length would neuter the load or if the powder is all burned.

    I'd imagine 24" is long enough but the above info would confirm with accuracy.

    A barrel of 24" will definitely do (much better than 26"). You may not achieve the factory-quoted velocity, but the need doesn't exist (never has).

    The barrel is 24", the last two inch of the barrel is muzzle brake which doesn't have rifling, so with muzzle brake included the barrel would measure 26", the velocity loss with a factory-ported (integral, not threaded brake) barrel is the same as with threaded brake?

    The factory barrel is 26", I believe, plus the brake (I once had a 460 Weatherby and this is what I seem to recall).

    It would make a good stopping rifle-cut the barrel to 22 inches and load 600 grain bullets
