I'm looking to reload some #4 buckshot for hunting coyotes at close distances (around 50 yards, give or take). I've never reloaded buckshot. Are there special wads needed for the bigger bb's, or can I assume that an ounce is an ounce is an ounce, and just use a wad for an ounce of shot. (or maybe an ounce and an eight) If you're willing to share a favorite recipe I would appreciate that to. Thanks for the input.
