After he got over his magnum phase, my father hunted a good bit with a barreled 308 Winchester, a full stock Steyr carbine. In that rifle he used 150 grain Interlocks and the Ballistic tips of the day which came in 100 count boxes. It was clear that those early BT's were softer. Fast forward about thirty years and it's me hunting with a 308 and 150 grain Interlocks and Ballistic Tips. I've found the current issue BT to be as good a penetrator, if not better.
