The Hornady LockNLoad Rifle Bullet Feeder (22 cal.) allows you to fashion your reloading press into a bunch-mounted ammo factory. The Hornady Lock-N-Load Rifle Bullet Feeder is designed for the Lock-N-Load AP reloading press. 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. Plus, it's compatible with other presses and uses the industry standard 7/8-14 die threads. The 22 caliber kit accommodates cartridge sizes from .221 Fireball through 22-6mm. The 30 caliber conversion kit will accommodate cartridge sizes from 300 Savage through 300 Rem Ultra Mag. Coupled with the Lock-N-Load Case Feeder, you'll realize dramatic increases in efficiency and reloading speed - up to 50% faster (based on experience and proficiency). The Hornady Bullet Feeder Die is case activated; the bullet will only feed upon contact with the case. One station is used to feed, seat and crimp the bullet.
