The RCBS Bullet Feed Die was precision-crafted from top-quality materials to ensure a lifetime of durable performance. This bullet feed die enables you to crank out reloaded ammo up to 50 percent faster when it is used in conjunction with the RCBS Bullet Feeder Pistol Kit. The RCBS Bullet Feed Die enables progressive-press reloaders to leave their feed dies in place on a removable die plate rather than removing and installing a new die plate each time. Simply install the RCBS Bullet Feed Die of the proper caliber, and you are good to go!
