Thanks Tim, I just noticed that post from BajaBill, I was hoping .429 but .430 is better than .432. I have a whole bunch of cast lead loads I received from an out-of-business indoor range that I want to burn up, I already have my 1984 Marlin, and model 44Taurus Revolver but any excuse to buy another barrel. I'd also like to know what twist BajaBill's new barrel is, hopefully 1 in 20.
