460 Rowland – .44 Magnum Performance from a 1911 Platform.
Just learned about a new wildcat cartridge. The 460 Rowland cartridge gives better than .44 magnum performance by switching the barrel, guide rod, and spring on a standard 1911 pistol. Felt recoil is similar to regular .45 Auto, but, due to the compensator, directly back instead of twisting up. The case, made by Starline, is 1/16″ longer than a .45 Auto case, to prevent chambering it in a regular 1911. Can be reloaded with standard .45 Auto dies.

I like the idea, but I’d be afraid to try it with my own M1911–I suspect that it might be a bit much for a ninety year old frame.
