gunsavy, welcome to FTF. I don't shoot, or load the 10MM. With that said, unless you have a uber stock of 10 brass, I would suggest that you hold off on that caliber for awhile. Sounds like you have pretty good coverage on the handgun calibers now. Although I have stocked up on components, and hand loaded ammo for 3 different calibers before I owned the guns to shoot them in- .22 Hornet, 9MM, and 6MM Remington, I do not suggest that you do that, unless you are into hand loading with the passion that I am. I enjoy the hand loading process almost as much as the shooting process.
There are a few on this board that have the 10MM itch, but they hand load their own ammo also..
