if it were me, i would go with something more common. 9mm, 40s&w, or the 45 acp. I haven't seen any 10mm rounds in quite a while where i buy my ammo. And when i did, it was quite expensive. If you are looking for power the 40 or 45 IMO would suit you and for plinking you could go with the 9mm. 9mm ammo is very reasonable and the .40 isn't far behind it.
