Wolfe Publishing has a CD of Gibbs info. and Quick Load lists it on its cartridge list. Z-Hat has a reamer available and dimensions on the 4D web site. Case volume is 71.5 +/- grains of water.
Performance should be equal to .300 WSM +/- if loaded to equal pressures especially if it is loaded to a "long" length. It should just about equal a factory .300 H&H.
doc..,
Thanks for the info. I'll pass it along.
