I have used Hornady's plan jane 140 Interlock for years on both deer and elk with out any problems. I have recently been playing with Hornadys 130 SST to see what I can get out of them. So for I've been able to match the accuracy of the 140 Interlocks but I have not been able to use them on game yet. The SST's will primarly be used for mule deer as I now have a 300 WSM
that I'll use on elk. If memory sevice me right the 130 SST's are backed by 59 grains of H4831SC.
