Go find a Howa/Weatherby Vanguard chambered to .300 weatherby mag. Have the barrel rebored to .366 and simply neck down the .375 H&H or neck up the .340 Weatherby.....both will run through that action nicely and you'll have all the power you wanted.....further bullets of 200 grains are easily made by shortening the 250 grain Barnes.....I've done it and it's easy to do.....further, while spendy, at $2.00 each bullets of 200 and 210 grains are available as is. You should be able to launch one at 3,000 FPS or more if that trips your trigger.

When it's all done, you'll have a very special and powerful 9.3.....and yes....you still won't have a .375 H&H.....
