The Hornady Lock-N-LoadA(R) Rifle Bullet Feeder is designed for the Lock-N-LoadA(R) AP(TM) reloading press. The Bullet Feeder Die is case activated; the bullet will only feed upon contact with the case. A single station is used to feed, seat and crimp the bullet. Sold as a complete unit for 22 caliber bullets, a conversion kit for 30 caliber bullets is also available, giving the reloader the versatility to load the two most popular calibers. The 30 caliber conversion kit will accommodate cartridge sizes from 300 Savage through 300 Rem Ultra Mag. Plus, it's compatible with other presses and uses the industry standard 7/8"-14 die threads.
