    density for max velocity.

    Accuracy is .093 5 shot 100 yard groups. and velocity is off the charts with a 200 grain bullet and
    126 grains of powder. (I don't want to give the load in fear that someone will try it in a rifle with
    little or no free bore)

    One of the members signature is "I DONT FEAR FREEBORE'' and I feel the same. and with a few
    special chamber dimensions accuracy is not a problem.

    Note; If you chamber the big 30 with little or no free bore you won't be able to use factory ammo
    and velocity will suffer because you cant load as hard .(The reason for going to the big Weatherby
    in the first place.

    30" with a 10" twist will run to potential. Wouldn't go much shorter in order to burn all that powder.

    I agree you did your research I replaced my bbl and have this in a Shilen air bbl
    Over factory it's night and day.
    Powder is the key , low and slow but drop tube to pack it in.
    Love H870 if you can find it or stock piled before. Use 129 gr but work up to that
    The only close I found is Vit. V n570 works for accuracy and speed working up loads .
    30-378 has been around a long time and still the best in the game.
    Long range flat is simple amount of powder ? Who has the largest case , don't read factory or reloading manuals you are pioneering work up a load .
    Bbl length cheats formula as slow powders burn down the bore. But matching bbl length to powder and bullet is range time .
    Still 30 bbl and case capacity , so 30-378 wins
    I've gotten 180 gr at 4000 fps FYI
