Coincidentally I was shooting that particular bullet this past Sunday in my 1903A1. Loads ranged from 18 to 22 grains SR-4759. Bullets were bhn 10, cast from wheel weights, air cooled. Accuracy hovered in the 1-2" range, 100yds., issue sights. Equal charges of 2400 perform about the same. (Initial load testing session with the newly re-barreled rifle, CMP Criterion barrel.)
With cast bullets, I only switch to 3031/4895/etc. when loading hotter rounds for hunting. I have no data stored in my head for those powders.
