With my incoming order of Federal 124g 9mm HST +P ammo and my good fortune of picking up a few thousand SPP I'd like to load my own plinking ammo that will replicate Point of Impact without being +P. I am assuming this is not doable with 124gr projectiles, as to reach the same velocity I would most likely be in the +P pressure range? Second assumption is I would be better off with 115gr projectiles running the high end of standard velocities?
