I have a new to me Lyman 457193 4 cavity mold. It makes a lot of big bullets fast. Empties a 20 pound pot fast too.
Every few months I shoot the NRA 200 meter lever silhouette match, and this has been going on 15 years. I like shooting a different rifle for a few years and then move on to something else. Mostly I like the smaller bore rifles but I am going to use my 1886 Winchester this year.
I have 8 pounds of IMR-4831 that is old and I want to shoot it up. And, I have this new, four cavity Lyman mold. Seems like a way to use up a lot of powder and lead.
Who has experience with this bullet and slow powder in the 45-70. I am going to work up Black Powder velocity loads with that plain base Lyman bullet.
Yes, I will say it ahead of time; I will be getting some un-burned powder in the barrel. And I'm good with that.
