What self defense 10 mm ammo does everyone recommend? Plus, because 10 mm is somewhat hard to find where can I get your recommended 10 mm ammo? Also, where can I get some cheaper 10 mm (not personal defense rounds) for range time? Bought a 10 mm at auction about 60 days ago and finally got a chance to shoot it yesterday. Really like the 10 mm. Store/range had only some Hornady 180 gr XTP and it was pretty pricey ($19.99 for 20). That's a little too pricey to shoot a lot of at the range. Wanna kill these ads?
