500 s&w loads

Check out www.loadswap.com for different load data, I've used it to work up loads for the 500 and other calibers.

I experimented with 600 grain bullets a while back. Started with 26.5 grains of H110 and worked up to 34 grains. Used QuickLOAD to predict the pressures, which were just under 50,000psi for the 34 grain load. Never saw any pressure signs and all cases dropped out of the cylinder after firing.
