The Redding Big Boss II Press is built with some of the same features as the original Boss press but built on a heavier frame with a larger ram and more usable ram stroke to make loading large magnum cartridges a breeze. Some of the improved features include an innovative spent primer collection system which has a tube that redirects the primers away from the press and the "Smart" primer arm that automatically swings into position during the ram stroke and flips out of the way when not in use. Dies and shellholders sold separately.
