My wife and I used a bunch of Fail Safes back when they were available, in .270, 7mm, .30 and .338. They usually worked very well, being easy to get to shoot and penetrating very similarly to Barnes X's.
But once in a while one would fail to expand much or at all, which can also happen with hollow-point X's, and the problem seemed to get worse toward the end of the Fail Safe's production life. You might want to shoot a couple into wet newspaper as a test, because wet paper is far more gentle on bullets than dry paper. If they don't expand well in wet paper, they might not expand on broadside rib shots.
