Loading, Crimping Guidelines for SinterFire Frangible, Lead-Free, Reduced Hazard Bullets.


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.
