150 gr '06 GK70 yards, yearling caribou. '09. Entrance wound. Exit wound at base of neck about the same. They expand immediately, and tend to blow all the way through. But I have no experience with them hitting major bone.

Nearly all that "blood shot" meat in this picture was saved by trimming out the membranes on and between muscle layers- wasn't nearly as bad as it looks here. It seldom is, with any bullet. Sierra GK work fine, and are generally highly accurate. My .338 WM will shoot @1" groups with Sierra GK handloads- at 200 yards. But since I hardly ever get a shot at over 100 yards, I use Hornady handloads or factory loads - most any brand shoots well enough....

I prefer Hornady or Rem Corelokts in my handloads, but I have a chit-pot full of Sierra bullets on hand to load, and feel no qualms about using them.
