Just recivied load Data from SPEER on their 41 caliber GDHP.
And guess what..... They list loads for handgun and a rifle.... the Marlin 1894.
Starting loads are 20.5gr. for H-110 and W-296, Max for both powders are 21.5gr. Both using CCI Magnum Large Pistol Primers.
Just thought it might help someone.
If you need more info let me know.
