I like the Speer Gold Dots. I first started using the 270gr. for my .44magnum. Sheriff Jim Wilson had a couple of articles in Shooting Times, along with other writers, and found them to be good performers on Elk sized game(deep penetration, excellent weight retention, and good expansion). I use them for hunting deer/elk/antelope and grizzly protection. My .44mag load is per Wilson's; .270gr SGD, over 21gs of H110 with cci non-mag primers. This load BTW, is max per sierra, and several other reloading manuals. I cronographed it a 1280fps out of my 5 1/2" Vaquero.
I just bought my first box of 124g. SGD's for my B92 in 9mm yesterday. I hope they will perform as well as their .44cal cousins, in a scaled down version. Any body have any data on their effectiveness in personal protection situations against 2 legged varmints?
