Any of the commercially available rounds out there are jacketed and will work fine; I have had good luck with Silver Bear, and the LVE ammo is the best I have seen so far, very good, very hot, and exactly what the guns were made to shoot; I have used the wolf and the Brown Bear as well, and while both functioned well, they were really dirty.
For defensive carry, the Hornady stuff is good; they are using their "xtp" bullet for it, and it's a good round.
