Loading of compressed powder metal bullets is a relatively new adaptation of a time-honored tradition. To ensure the success and safety of our customers, SinterFire's R&D team has conducted exhaustive testing to develop proven reloading techniques for frangible bullets. Please follow the listed guidelines below for proper crimping.
1. Adjustment of the bell/expander die
The case mouth should be belled/expanded the minimum amount to permit proper lead-in of the bullet.
2. Bullet Seating
SinterFire® projectiles are designed with a tapered length to accept a taper crimp at a pre-determined depth. They should always be loaded to the suggested OAL.
3. Final Crimping: (always taper crimp)
Very little taper crimp is required, less than cast, jacketed or plated bullets.
Prior to finalizing the set-up of the loading operation, the bullets of several loaded rounds should be pulled from their cases and inspected for crimp compression. A properly crimped bullet should not show signs of crimp compression or indentation by-or-at the case mouth. Over crimping will result in a compression and/or stress fracture at the case mouth. This will cause the bullet to break off.
Hand loading of ammunition should be done in a safe manner and by individuals knowledgeable of ammunition components, the loading process and the associated hazards. Safety is always a priority when loading or handling ammunition and components and individuals not knowledgeable of the process or hazards should seek professional assistance.
Since reloading practices are beyond our control, SinterFire®, Inc. disclaims all liability for damages that may result.
