I've been playing with a 10mm Hunter, dreaming of the ultimate 6" Limited Tanfo and wondering: has anyone had any issues shooting .40 out of a 10mm chamber? I know in theory the round could slip in front of the extractor and slide into the chamber, but has anyone had that happen? I haven't had any issues, but I've only fired maybe a box of ammo though it, does anyone else shoot this way and have some experience to share?
