[QUOTE="Bravo 4, post: 2340131, member: 8873"] They are a rapid expansion bullet, if you drive them too hard they may come apart on you. The key is to load them heavy for caliber. This will do two things, first cut down on velocity. Second is it gives it more shank and more to hold together for penetration & good mushroom. Example: I load the 139 SST in a buddy’s 7 RemMag. He doesn’t shoot distance and thinks that if a bullet goes in and comes apart that it dumps all its energy into the animal. I am the opposite, I want a heavy for caliber for not only better penetration but for “better” long range external ballistics (usually higher BC). I also want something that if I punch a shoulder that it will penetrate, and I prefer an exit wound. I was loading the 162 SST in my 7 RemMag and it would expand fast (as it’s the same design), give good penetration (almost always leaving an exit, even if a shoulder was hit) and has higher BC. The difference is night and day between the two bullets, even though the same caliber. Grouping a type of bullet into one category is not a fair analysis. I’d hunt elk with the 162, no way with the 139 (at least out of the RemMag). I’ve shot deer with a 225 SST out of a .338 Edge, that bullet seems rather tougher, as I’d expect for the larger caliber.
