I can't find the link, but saw where someone else had used them out of a 300 WBY on deer. Afterward they tested them in ballistic gel. At magnum speeds and at around 200 yards or less they came apart. At 30-06 and 308 speeds they did fine as well as at longer ranges (200+) with the magnums.
Based on what I've read they are probably no better or worse than Nosler Ballistic tips on game. But are almost 1/2 the cost with slightly better BC's. I've only experimented a little with the 200 gr bullets and accuracy was very good.
