Everything you need to begin making your own ammo is included in the RCBS Rock Chucker Supreme Master Reloading Kit. With practice, it's possible to reload up to 100 rounds of ammunition per hour. The ambidextrous handle and easy operation make this a versatile unit. The Uniflow Powder Measure dovetails well with the M500 scale. Just add the proper dies, and you'll be able to reload most rifle and pistol cartridges.
