I would like to try the 385gr Great Plains projectiles. I have N120, but I'm wondering if a slower powder would be better.
I can get some IMR3031 locally, which was documented on the forum as workable for 400gr projectiles in Savage 10ML's. Would it be foolish to start well below the lower loads listed here? (eg 60-65gr 3031 with 385gr projectile.)
With brass cartridge reloading I know that the minimum loads are important, because of the set volume of the brass cartridge. The ratio of powder volume to air volume in the brass cartridge can cause problems when there is too little powder and too much air. Conversely, with a smokeless muzzle loader can I safely load smaller charges given that I'm loading the projectile directly against the powder column? Is that a fair deduction, or is it likely to cause safety concerns?
I have a healthy supply of Varget and RL16 for cartridge reloading. Would it be worth trying powders like these which are slower than 3031? From reading through old posts I'm seeing rather large charge weights of these powders for pushing big projectiles (100+ grains?!).

Maybe this will help some as a guideline to where burn rates apply to different bullet weights. As always this is a guide, you must test in YOUR gun. Start low and work up as with any load development. These loads have been shot in Savage ML's. I do not know how that compares with the ULA. I do know that some are real rompers & stompers in the Savage.
