Critch, most of the commercially CAST bullets are relatively hard. If you find bullets that fit your bore, you probably will be fine.
You'll note that I stressed the word 'cast'......a few bullets are swaged, not cast, and swaged bullets are quite soft. The major bullet companies, like Hornady and Speer, sell swaged bullets. Swaged bullets are excellent for wadcutters and other low speed applications- usually not so hot for fast loads.
Swaging equipment is more expensive than commercial casting equipment- which means only the major bullet companies swage bullets, as far as I know. All the smaller lead bullet companies cast bullets, so they'll be harder-harder alloys cast better in high volume casting equipment.
