I had my TC Renegade barrel relined to .38 cal. with 1:14 twist and will be shooting a 300 gr. grease groove boolit using pure lead for casting. I am now waiting on my Accurate Mold to be shipped. I would like some suggestions on what grade, charge weight, and brand black powder I should use for target shooting. I use OE FFg for my BPCR's with great results.
