Wondering if anyone has tried hand-loading Montana Bullet Works 44 Magnum 255 grain Keith style gas check bullets. I’m using IMR 4227 powder. No loading manual I have seen cite this particular bullet. There is data for 240 grain and 265 grain jacketed bullets, but nothing on 255 grain Keith style GC semi-wad cutters. The bullets are significantly longer than the 240 grain semi-wadcutters I normally use. Has anyone else loaded these MBW bullets?
I’m starting at 19 grains of 4227 and loading to 1.65 inches COL. putting more powder into the case than that may be compressing the powder.
Wondering.....
Follow up: I’m using this in a Marlin 1894 lever gun. The bullets load into the tube and cycle well.
