I’m slowly working toward accumulating supplies to cast 45-70 boolits for a deer and hog hunting application. The idea is a 405gr flat nose (Lyman 457193, 457463, RCBS 45-405 etc) up around 1500-1600fps or so.
I don’t care for the idea of completely non-expanding, but I’m sure not looking for giant mushrooming either. More like the bullet should “upset” upon impact and just continue driving after that.
My first thought is to blend maybe 3 parts 30:1 with 1 part Lyman #2. Should maintain a heavy weight bullet (avoiding excess tin) while getting a little hardness with the watered down antimony. Using online calculators perhaps 10.7 BHN or so.
Thoughts from you experienced hunter out there?
