Randall,
Exactly, and Nosler also controls how much the jacket around the front core peels back by its thickness and taper--which also contributes to the high weight retention of large-caliber, heavy Partitions as I described in my previous post.
It always amazes me how many hunters think they can extrapolate how ALL bullets of a certain brand and name work from the results of SOME bullets of that brand and design. Every bullet company I know of tweaks the basic design depending on caliber, weight, intended use, etc.
