I'm hoping to make my first attempt at cast bullets in a rifle soon. The rifle is a pre-64 Winchester 94 (built in 1961). The mould I have is a Saeco #316 150gr FNGC, no gas check or sizing die yet and I have not slugged the barrel so I am flying blind and expecting the worst. But I just can't wait to try it anyway.
Bullets are cast with ISO 96-3-1 + tin, and weigh in at ~153 grains straight from the mould. Base driving band measures .310 and the upper 2 measure .311. I have tumble lubed the bullets twice in 45-45-10. My plan is to try 13.5 to 16 grains of 2400 in .5 grain increments. Does this sound like I have any hope of success? Or should I just wait and order gas checks and a sizing die?
