RE: 7mm wsm experience?
Here we go again. "The BST's are like TNT blowing up" junk again. One word: BUNK
They will expand very rapidly if you hit bone at close range but fear not yee of bad judgement or poor marksmanship, the core will pass through the shoulder into the body cavity. They do not blow up as most make it sound. I spend half of my hunting season butchering deer, and I do see many that have been poorly hit with BST's, the fact that I am seeing them is proof enough. I have used the BST's in .270 Win and .270 WSM and they work perfectly as designed and intended. For those of you choosing to make a career of 50 yard rifle shots right into the shoulder, get the copper solids to make sure you break both shoulders so God forbid you don't have to do a little tracking.
