RE: HOMEMADE DEER MIXES???
Well, .308, I personally do not condone hunting over bait (plus it' s illegal here in PA). To each is own though. I only put out salt blocks in my back yard so that I can enjoy watching deer from my back door, not hunt them.
I have had great luck with the homemade mineral lick method mentioned by Carolina. The deer have a huge hole dug in the dirt where I had placed the salt.
Good Luck
