Hello,  I picked up a new to me .256 Super Mag (.256 MAX.) in a 12" MGM Encore barrel.  This is the .256 Win Mags big brother built with .357 Max brass vs. .357 Mag brass.  Does anyone have any published, made-up, tried, or proven load data for this wildcat.  I saw few articles on it several years back but like a dummy I never kept any of them.  Any help would be greatly appreciated.
Thanks, Mike
