Howdy. I've recently acquired 60 lbs of Lyman #2. As you know, the Bhn should be 15. I mainly shoot cowboy guns (SASS/CAS/NCOWS) with either smokeless or black powder, and with low velocities (Please note--I shoot Warthog charges, not powder puff loads.) I also shoot BPCR. Because it's b.p., the velocity is low compared to smokeless.
I've searched without success, both here and on the web, for a simple recipe to soften and extend the Lyman #2. I have some close-to-pure lead from stick-on WW's, cable sheathing and muzzleloader balls. I don't have Microsoft Excel so the various calculators can't help me.
I'd like to cast bullets that are in the 10-12 Bhn range for the cowboy guns, and possibly softer, like 30-1, for BPCR. I'd be grateful if someone could suggest how much pure lead I need to add to the Lyman to soften it and make it last. It would be great if someone could answer both in percentages and actual weights. When it comes to math, I definitely ride the short bus.
Thanks!
