Sectional density sir.

124gr XTP: .141
185gr XTP: .130

That's comparing a 185 and it's still markedly less sectional density. What that gives you is a VERY large wound, but not a deep one.

I personally think trading expansion for penetration is not a great idea (all within reason of course).


I would not be predicting penetration on SD alone, seen it not work that way many times.


I get that, but look at ballistic gel tests.
