The lead sheets used for flooring in the Sears battery room I pulled up has a BH of 5. I mix it 16:1 with pewter for a Bh of 7.8 and 50//50 with COWW with a Bh of 10.4. Makes some great Sub MOA expanding HP boolits. I might cast up some HP boolits in 5BH flooring and insert them into a sabot to try in my 50 cal TC Omega muzzle loader along with 150 grains of tripple 7 pellets.
