Alright y'all, tell me what you think. I'm interested in working up a load for 150 grain cast bullet in my Winchester Model 94AE in 30-30 Winchester. I'm looking at using IMR 8208XBR. I've checked in my Lyman Cast Bullet Handbook, I'm using the Lee # 309-150-F bullet. In the Lyman there is a load for IMR 3031 which is almost exactly the same burn rate and both are extruded propellants. The start charge weight for IMR 3031 21.8 grains, I'm looking at a start charge in the same area for the IMR 8208 or maybe slightly lower, say 21 grains.
So, you guys who have more knowledge than I please weigh in.
