I use RAKS deer mineral and have had great success. I also use a couple of feeders in the spring with Double Lung Outdoors Massive 40 protein pack mixed with corn. What I have been told is put out a couple of mineral spots because some will be used and some won't. Determine which ones are and keep mineral there. I've checked cams year with cam #1 having 880, 1300 and 1880 pics; cam #2 having 1330 and cam #3 having 330. Stick with it and they will come!
