I use the Nosler in my 7mm mag. I'm notsaying that the Barns are not good or effective butI don't believe that the Barns are worth the cost. I also use the Sierra Game King which is even less expensive and I believe as effective. As you know the well placed shot is most important. I have used the Barns and I don't see any real diffence when harvesting whitetails. I don't think the deer know the difference either.
