I always wanted to try them but because of their price kind of looked at them only. Then I found a shop that had the Barnes MZ Expanders, ten on a card for $4.99 each on clearance. So I bought all 15 cards. These things really do shoot. Some of the best groups I ever shot are with these Barnes bullets. Sure am glad to hear they do as they claim on game. I have not had a chance to test that part of them yet. Congratulations on the deer.
