The caliber specific, tube fed RCBS Pistol Bullet Feeder .40-.45 82350 has been created to be used in conjunction with any 7/8"-4 threaded progressive press. Each of these Bullet Feeder Tubes from RCBS holds 20-25 bullets depending on weight and profile. The RCBS Tube PBF Bullet Reloader places the bullet into the case mouth, for proper alignment, to be seated at the next station. Another added benefit is that it can be used with jacketed, plated, cast or swaged lead bullets. The RCBS .40-.45 PBF Bullet Reloader Tube allows you to increase load output up to 50%.
