It would be hard to recommend an ammo type. I know that where I live, it would be pretty much impossible to find plain lead bullet ammo in those calibers. If there were a range nearby that imposed such a regulation, I would go somewhere else. I know that I could take up reloading, but it's not something I care to do.
You could see if you can order ammo from one of the major ammo retailers. As long as you stick with ammo from the major makers, I don't think it will matter which one you get, as long as it functions in your pistols of course.
