"use a real hunting bullet"
do you mean one that shoots well, has complete penetration, near perfect expansion, and performs consistently? Or is there some other qualities I'm unaware of that you seek in your "real hunting bullets." Because if not the SMKs worked as desired.
How many of you that are spouting off about the inadequecy of the SMKs have actually used them, or tested them in a medium that allows you to examine their potential.
I'm aware that Sierra does not recommend their use, but guess what they worked great, the buck died quickly, what more do you want. I'm willing to guess most of us use products for other than their intended use. My rifle for instance, wasn't designed as a hunting rifle, but it worked great too.
