I aquired a box of 250 130gr .277 Hornady SST's from a friend and I was thinking about loading up some mild rounds for my wife's .270 WSM to get her used to shooting something that can whack down a elk. The problem is that I cannot find any information on loading these SST bullets, but I can find a plethora of good loads using Hornady's SP/Interlock bullets. What the heck is the difference? I heard through the grapevine that you can load the two bullets similarly, but I'm not taking any chances. I've heard good things about the knowledge on this site so I figured this would be a good starting point.

Any help would be greatly appreciated.
