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. The 40-10 TNT Crimp reloading die has an alloy body and anodized finish 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
