load data on 375 H&H

[carpediem]

Hello All:

I am looking for load data for a cast bullet in a 375 H&H.  I have the Lyman cast Bullet Manual and there are a number of loads in the 375 H&H section however, all loads stop at about 1700 ft./sec.

I am looking for loads that will do up to 2200 ft./sec.

I have three different types of bullets:
   250 grain plane base
   270 grain gas check
   300 grain gas check.

Any help would be appreciated.

Kindest regards and Merry Christmas,

Max

You might well find someone that's pushed cast up that fast in the H&H.  I've only tried cast in the Win 94, although I'll get to it in the H&H.  

Generally you'll find you have to work up to a higher speed paying attention to alloy, hardness and lubrication.  Generally 1800fps is considered tops for accurate loading unless extreme measures are taken.
