Here's a wrinkle: It seems to me that size/weight must at some point make a difference even though substance, construction and S.D. Remain the same. Take bullets of a S.D. Of .250 which for most standard cartridges most would agree is on the wee side for elk for instance. In a .270 this might be somewhere around 140 grains; it might exit; it might not. But a similar bullet (construction, S.D.) of 150mm and the size of a loaf of bread and at about them same vel (case capacity stays proportional)--does anyone doubt that that would exit? Probably, not even here.
MDs notes show no significant differences between the '06 and its progeny but my extreme example from common sense tells us that at some point size will be "a better killer". It seems silly in the telling and yet that is what this whole thread is about-- does .031" make a difference on the same range of creatures?
Apparently not at this point in slight difference but at some point it will.
