The 41 Remington Magnum was developed by Remington introduced in 1964 in the Smith & Wesson Model 57. The 41 Magnum was envisioned a revolver cartridge for law enforcement use that offered more power and penetraion than the 357, but with less recoil than the 44 Remington Magnum. Using case length of 1.290-inches and a .410-caliber bullet, the 41 Magnum is an extremely effective and powerful revolver cartridge. The most common standard load features a 210-grain bullet at 1300 feet per second, yielding 790 foot-pounds. Although adopted by few law enforcement agencies, in part because of recoil and in part because of the near-wholesale shift to semiautomatics, the 41 Magnum is an excellent load for handgun hunting, much more effective than the 357 Magnum for deer-sized game. It is currently seeing some resugence in popularity. -- Craig Boddington
