I got a Benjamin Bulldog about a month ago, with the idea of using it for deer hunting. The only mods I've done to it are adding a Pitbull mega-moderator and depinger to it. A guy I work with cast some 158 grain .358 semi wadcutters in pure lead from a Lyman mold, and the accuracy was abysmal - I hit the target twice, one slug looks like it keyholed, and the rest went high, low, left, and right. I want to cast my own slugs to hunt deer with - I have a melting pot and plenty of scrap lead, both pure and WW metal (old lead ones, not modern zinc). Can anyone here recommend a mold that would suit my purposes (deer out to 50-60 yards, from a stock Bulldog)? And should I use pure lead, or something harder like WW?
