GAEP BN4 CRIMP FINISHER

BN4 Crimp Finisher: Optimal use is with very progressive, slow burn-rate powders such as those used in 1-1/4 oz. loads or heavier. Excellent for heavy field and magnum slug loads.

GAEP Rotational Finishing Crimper for Folded Star Crimps is a specialized tool designed to refine and perfect the crimp on shotgun cartridges after the initial star crimp has been formed. Once the star crimp has been set, this rotational crimper smooths and finishes the top edges of the cartridge, providing a clean, uniform appearance. It also flattens the top portion of the crimp, ensuring a secure, consistent seal for the cartridge. This finishing tool enhances the overall quality of the shotshell, improving both its aesthetic and functional integrity for optimal performance during firing. Ideal for handloaders and ammunition manufacturers, it delivers precise, professional-quality results every time.

* IMPORTANT NOTE ON RPM: GAEP crimp heads are optimized for operation at 1100 RPM, which is the standard speed for their motors. Many hand drills and some drill presses do not reach this rotational speed. If you experience crimping issues with GAEP products, the first step is to verify that you are operating at the correct speed.
