I've tried Lucky Buck and all the others. If you take into account the salt levels, what they cost, and how the deerr use them there is nothing that works better than the 3006 mineral. I use the plus Protein formula. It only has 15% salt. If I wanted a bag of salt I would go to the Sams and buy salt.
To say that Lucky Buck adds more salt to get more mineral into the deer is BS. Must be another salesman.
The only one that beats lucky buck with BS is the tropy rock. They claim all the minerals a deer needs and when I looked at the tag it was 99% salt. Get real and dont waste an old mans money.
