The 500 grain RN both soft and solid have done good work over the years in the mighty 458WM on African large game, the Big Bears up North and all sorts of game down under, all recorded in the pages of this thread by others. Also we know the flat Point is better in all phases of terminal ballistics and we are grateful for the bullets that have been developed along those thought lines. If you look at the Copper bullets with hollow points in their internal workings, you see rapid action to get weight forward and flat on front. Of course about every other type of bullet action is designed into someone's bullets but the key to through and through is to get weight forward and overcome tissue resistance. The Hammers do this by shedding petals that become secondary projectiles while the weight forward and flat pointed solid now moves on.
Sir Ron and others have much to offer us in testing and research in this thread. Best Public Sourced work on these topics ever.
