My vote is for the 165gr SGK. My wife has used them for years coming out of her 30-30AI. They have always hit a happy medium between expansion and penetration.
I also used them in my Remington 788 chambered in 308Win to kill some big Maine deer.
My only expierance with the Hornady SST's is from my 6.8SPC (120gr). They kill hogs ok,however they always seem to shed the jacket. Pretty much the same report from other 6.8 shooters. Even at the reduced vels over a 270Win. --- SAWMAN
