With so many adjustable mold group buys going on I've had this pondering floating around in my brain a fair amount. This is more of a rifle question as I'm thinking as most of us tend to carry one load in a wheel gun/revolver and know where that one load prints at longer ranges, whereas we may not mix loads in practice afield for longer shots. But for rifle it may be desired to carry a solid and a hollow point option. Combat stacking isn't my idea here but it falls in line with what I'm pondering.
Say we have a 30/06 that we have zeroed for 150gr Lee flat point bullets and we want a hallow point cast that will duplicate the zero already established. If we took the same 150gr design and just made it a hollow point (say a 120gr HP) the impact would be lower at moderate ranges(most of the time, in theory). But if we took a 180gr mold of the same design and made it into a 150gr HP mold (same bearing surface) I'm thinking it should print pretty close if not the same to the original solid load. Right?
I understand bullet OAL does play a factor in this but I'm not sure how if the weight is the same between the solid (shorter) and the HP (longer) with both having the same bearing surface (same pressure). I've been reading Rinkers book on "Understanding Ballistics" as generously donated by a forum member and its left me to the conclusion that well....simply put I need more molds if I'm to have rifles that print the same with solids and hollow points of the same general design.
