While not directly for the 350 Mashburn Super Magnum, the data below may help

250 Grain Continued

Or... maybe start with reduced 358STA data. Out of interest, has the taper been taken out of the original case a la 358STA or left as per the 350G&H??
Cheers...

taper has been taken out - looks like a weatherby rounds- rounded

There is a wildcat 35 Wby from a while back, possibly this is one of those. Maybe post pics and dimensions of the case and we can get more specific. I would start with 358 Norma Mag data, and stop around 358 STA starter loads. - dan
