Mike, if you are using these reloads just for practice, any fmj or coated bullet will do. I use delta precision coated bullets in my limited gun for practice and competition. Some of the shooters that I know still like the uncoated lead bullets. They are a lot cheaper, but can be a mess in barrels. If you are burning through a couple thousand rounds a month, it is a consideration. But be aware, if you choose uncoated lead, depending on what handgun you are running them through, you may have to replace the factory barrel with a competition barrel. Glocks especially.

.....they all sell bullets in bulk. Some of them require a purchase of at least 1000-2000 at a time. Best of luck
