The Fail-Safe is a complicated bullet that was difficult to manufacture and expensive to sell. Not enough people were buying Fail-Safe ammo, so it was dropped. Fail-Safes were not the most accurate bullets ever, but they were plenty accurate enough, and their performance on game, from my experience, was exemplary. I’ve used them in .270, .30, and .338, both here and in Africa, and regard them as the top of the heap for a controlled-expanding bullet. In fact, I just spent a bunch of my own money on six boxes of .270 WSM Fail-Safe loads which I found in a Bass Pro Shop near Denver.
