This single cavity 538 grain .450" diameter "Creedmoor" type bullet mold is designed with the long range muzzleloader in mind. Works great in 1-18" twist barrels, 1.42" long and bearing length .910". The mini-grease groove bullet means you must wipe between shots. This design also works for black powder cartridge rifles that are shooting bore diameter bullets.
