I have been feeding deer the Lucky Buck Minerals on a piece of land I hunt for 3 seasons now. I can't tell you the growth I have seen. When I first started hunting, I could not even find a 110" buck, last year we took a 141" and a 135" buck. This year I already have some monsters on film that I think will be in the 150" class. I keep it out year round. Here is my latest big boy eating the minerals.
