I was a late member. I posted in the HHI Mailbag under my name Jeffrey Locke and it was about the 44 magnum and the JDJ 310 grain cast bullet. I bought an aluminum cast bullet mold for that bullet. JDJ wrote that the 454 Casull could only match the penetration depth of the 44 magnum loaded correctly for deep penetration of big game. I would join and contribute articles too.
