I have some 311284 bullets that I inherited from my Dad, along with some powder and his old manuals. The bullets measure out to .314, and weigh 220 gr lubed and checked, which I'm hoping will work well in my shot out, counterbored M44. It slugs out to .316/.305. While looking through my Dad's Lyman 45th Edition manual, they have a 220 gr jacketed load of 35 gr of IMR 3031 pushing it to 1960 fps. I'm wondering if I could use that load to push my 220 gr gas checked cast bullets. Velocity seems about right for cast. Worse come to worse, I'll have leaded my barrel.
Think it'll work?
