Nitro450exp - why can't you hunt with your DR? They're OK here - or are you talking about shotgun-only areas?

RB's are easy to load, Jeff Tanner makes any size you want and trap-wads are free for picking them up at local trap ranges. Cut the base wad off and there's a gas check and cup-up ball centering wad for the ball. Merely use whatever in-between fiber wads that are necessary for getting the proper crimp height for a star crimp. Even a lee loader makes good RB ammo.
