The point is to minimize exiting bullet mass. Recovering the hog is secondary to killing it safely. There are times when getting a good head or neck shot is tough, especially when there are 5 + hogs milling around a feeder or hog toy, you often get high shoulder shots on the larger hogs but the neck and head are hidden by smaller hogs. The SST has been getting the job done, I would just like to see less bullet mass exiting on the head and neck shots I take with the 308 and want what does exit to be just fragments.
