I've loaded some BP cartridges for my 38-55 and new 40-65 CPA. I've read confusing and conflicting instructions. Some info says load enough with a drop tube to touch the bottom of the bullet using a .30 card and Goex doesn't like to be compressed more tham 1/8th of an inch. Others say fill it up and compress. My load for the 40-65 is 51 gr of OE 1 1/2 the compresses about 9/16 of an inch using a 400 gr Snover bullet from Montana Bullet. Is there a right way to do this? Thanks
