Not confusing at all. full metal jacket is a lead bullet incased in steel. Hollow points are bullets that are designed to expand and fragment upon impact. The biggest difference between a fmj bullet and a hollowpoint is expansion. A fmj does not expand as well as a unjacketed hollowpoint. Yet at point blank range there is not as much expansion. +pp is personal protection ammunition that is grained higher then your standard target round. Each bullet has a certain amount of grain (gunpowder) , 170 grain , 240 grain etc. +pp ammo just has more gunpowder in it.
