I understand part of what you're saying considering that at a distance of 25 yds you're practically on top of your target BUT... let's say I've sighted one of my .50 caliber rifles dead on at 50 yards with patched round balls using a 70 grain charge of FFg. At some point during my shooting session I choose to load a 370 gr. MaxiBall conical bullet with the same charge and that bullet is going to hit higher? I don't think so.
