These days, you will probably have to use whatever you can find.

Under normal circumstances, I use ball ammo, either FMJ or hard cast lead (my reloaded ammo) for the majority of my practice as ball ammo is cheaper than hollow point. Factory hollow point loads for defense and a little practice for sight in and familiarization. My practice ammo is always the same bullet weight and velocity as my defense ammo.
