Since this is the ammo section and not the reloading section I'm going to guess you don't reload so here are a few good choices for factory. (IMO of course)
Grizzly Ammo My first choice!
Double Tap
Federal Ammo
Buffalo Bore
I'm sure there are others but the above are a good mix of choices and all considered quality ammo.
(I like Grizzly Ammo and Cast Performance bullets best!)
