Howdy,
I've recently gotten another friend excited about reloading, and he's really interested in reloading for his McMillan Tac-50 bolt gun. We're all set for equipment, but as this is foreign territory to me, I'd like to ask for some tips on reloading the 50 BMG. He'll only be shooting j-words out of once-fired commercial brass (for now). What are some good powders for use in a bolt gun, including surplus powders? The furthest range he has available to shoot up here is 200 yards, so super long range isn't a concern right now. Thanks for any advice you may have.
