Good morning. I just picked up some Oregon Trail true shot .431-300 WNFP for my 444 Marlin from a straight shooter on this site. and it seems all my books stop in the 260 range for cast bullets for the 444 Marlin. Does anyone have any published data they wouldn't mind sharing? These are gas checked
I also wouldn't mind hearing about your favorite loads as I just picked this rifle up and am just now starting to experiment. I did order the custom Lee factory crimp for the Hornady 265 FTX in a shortened case.
