John- sorry for the later answer, but you should be able to order one direct. Damage? Well you can do plenty, if the are not taken care of. Even carbide. One reason I deprime, and clean ALL primer pockets now. Several years ago, I scratched 3 sets of carbide 45ACP dies- bottom line was crud in primer pocket. ?? So it goes. I am a big fan of the 10MM, in fact, I just picked up an AMT Longslide Hunter MDL last night. Should be here next weeek.
