Product Information

Doubletap was started by Mike McNett, President and CEO, in his Salt Lake City garage in 2002. Since then, Doubletap has developed a reputation for powerful, reliable and accurate ammunition loaded with a variety of premium bullet options. With their "no punches pulled" style of building ammunition Doubletap uses only the best components available to manufacture the highest performing ammunition possible. With special attention to quality control and precision craftsmanship each individual round is inspected and handled by Doubletap employees that share a passion for shooting and hunting resulting in the highest quality assurance possible.

Doubletap 450 Shot Magnum Cartridge ammunition should only be fired in pistols that have been modified to handle the increased pressure of this round. The 450 SMC is based off the 45 Super but features a small primer pocket allowing for stronger web area of the case. Several gunsmiths specialize in converting pistols to 450 SMC. The case length is the same as standard 45 ACP so the same magazines and reloading dies can be used. These hardcast semi-wadcutter bullets offer the deepest penetration possible in this round. An ideal choice for hunting and for protection while hiking or camping in areas known for large dangerous predators.
