Not sure if this has been done before but how about a 300 H&H case necked up to 338? Am sure there must be a way to figure out the velocities on paper before the next step assuming it hasnt been done already!

Mr Holland is pretty sharp today.....I'd have simply said it's called the .340 Weatherby...... well close!!!

Plan on the .338/.300 HH to get you a 250 grainer at about 2,700 FPS

Quality Cartridge even lists brass for it.

Pacific list the reamer.

Thanks gentlemen. I guess there is no point reinventing the wheel!

You will find that most of the ideas have been tried. Or at least there with very minor differences. I spent a lot of $$ (at least for me) and a lot of time building up and testing my PDK series. Only to find 10 years later I had a Gibbs using 280 brass and 40 not 35deg shoulder.

LOAD FROM A DISK has the numbers in H2O. 338 OKH=69 338 Lapua=114.8 338 Ultra=107 338Win=83.5 340 Weath.=99.6 and 338/300 H&H =87.6

If it's any consolation, you're not the first one to discover the benifits of a wheel on society.
