I have a special affection for lever action rifles and simply had to have a .500 for my lever guns! While a 50 Alaskan is a fine cartridge for the lever guns, the choice of bullets is but a small hand full in .510 caliber that will function properly in a lever gun. Quite the opposite is true of .500 caliber in which there are literally dozens of bullets to chose from in many weights and configurations.
It was a very simple operation to take a normal 50 Alaskan case and squeeze it down to .500 caliber and start shooting. We converted existing Winchester and Browning M71s and the cartridge is a perfect fit for the Marlin guns chambered in 45/70. My rifles all have 18 inch barrels and are extremely handy and fast in action.
I consider the 500 gr Hornady is an excellent conventional bullet for this rifle and cartridge combination. I have used it in the field on several animals of note, and tested it extensively at many different velocities up to 2100 fps. The 50 B&M Alaskan is capable of running the 500 gr Hornady at 1850 fps, I would consider it an extremely good combination for thin skinned dangerous game. These bullets, along with many other .500 caliber bullets, such as the 400 Sierra and the 325 Swift are excellent alternatives for the 50 B&M Alaskan.
Also available now is the North Fork 450 gr Premium Bonded, along with Safari Lever Solids and Safari Lever Raptors from Cutting Edge Bullets. This gives the 50 B&M Alaskan more versatility than any lever action cartridge I know of. The various bullets from Cutting Edge and North Fork boost the capabilities of the 50 B&M Alaskan to entirely new levels of performance.
Being a rimmed cartridge it is a natural for the Contenders and Encores, which SSK Firearms has taken a good deal of interest in, and many of these have been built and are in the hunting fields. It is also an excellent for many of the single shot rifles like the Winchester 1885 and the Ruger #1.
