Mike,
I have that bullet in my work-in-progress BTB QuickLOAD file. What are your objectives? Velocity, pressure limit, etc.? 54 grains of Varget looks like about 80% case fill, 42,000 psi and over 2200 fps from a 24" tube. Ballistic efficiency is close to Hatcher's promised land of 30% for high power rifles. Should be a good combination. You'll probably want to work it up with magnum primers to pressurize the big case well.
