The 10 is a great round. For reloaders, maybe the best centerfire pistol round there is. While I was seduced by the spectacular ballistics of some 10mm ammo, the cartridge was intended as a service round that allowed more ammo in a pistol of conventional size than did .45 (think .40 Hi-Power). Turning it into a magnum was essentially a mistake; not in the sense that it was regretted later, but in the sense that the round was never supposed to be the .41 Mag of pistol rounds. When the 1911 didn't die, as many thought it would in the '80s, and the Bren Ten didn't take the world by storm, there wasn't really much need for the 10. Even Col. Cooper admitted that there's little need for a self-defense round that shoots flat out to 75 yards. That said, there's all kinds of uses for the ballistics of which the cartridge is capable, and if you like to plink, hunt, walk in the woods, pack for protection, etc., there's a 10mm round that will get the job done. I was reading that the original Norma rounds were loaded to a max pressure of over 44,000CUP (more than double .45 ACP), but that modern, American-made ammo is loaded to about 35,000 (same as 9 and .40).
