Range ammo is generally fmj/steel cased ammo, defensive is generally hollow points. ... Defense ammo usually comes in boxes of 20 and will probably be about 2-5 times more expensive per round. It's nearly always hollow point bullets which expand on entry which causes more of the energy to dump out and damage the target.
