    Can anyone tell me what I can expect for velocity from the heavy MKs like the 220 and 240's in a standard length .300 Weatherby cartridge, throated short?

    I am considering this cartridge for a rebarrel job on a Rem 700 and while elimnating the freebore would be more conducive to accuracy, I am wondering how deep I'd have to seat these to fit the magazine and what the resulting velocity would be.

    Anyone know? TIA.
