The Mighty Armory 40 S&W / 10mm TNT Crimp Reloading die allows a tighter neck tension. The taper crimp die is your finishing die that tapers the cartridge case mouth to achieve a round with perfect SAAMI spec angle. Once the bullet is seated, the crimp will match spec sizing to provide consistent and uniform tension around the circumference of the bullet; from .418 to .420. This helps to prevent bullet setback, ensures reliable feeding, and maintains proper alignment and stability during firing.
Choose either die option depending on material preference (steel die body or alloy die body):
- 40 S&W, 10mm TNT Crimp reloading die with alloy body and anodized finished with a steel micro-polished crimp butt.
- 40 S&W, 10mm TNT Crimp reloading die with steel body and black oxide finished with a steel micro-polished crimp butt.
Pro Tip: We recommend using PEG75 Lanolin mixed at 7 ounces of 99% alcohol and 1 ounce of PEG75
