10mm Magnum (10mm Mag) Retail Ammo Options

Mod'd my S&W 610 to take 40S&W, 10mm Auto, and now 10mm Magnum, a bit of a wildcat round that is comparable to the Remington 41 Magnum. Luckily, a little bygone company called Maine Cartridge Company has some retail ball 180 grain ammo floating around for cheap on the web. Moreover, DoubleTap Ammunition out of the great state of Utah has a nice listing of high powered 10mm Mag in all kinds of bullet weights and classes. A hardcast 230 grain they offer if going to be my model round for round development. But with these two options, anyone wanting to shoot 10mm Mag is probably going to be forced into hand loading. There isn't enough retail ammo options to make this round more popular -- yet.
