The only cure I've found for hogs and coons is the Double D Gravity Feeder at wildernesscalls.com.We bought two to start with a couple years ago then three more once we found out how effective they were and are getting three more in a couple weeks.Our food bill has cut in half since using them due to no coons,hogs and spoilage.We have the Big Buck which holds 350lbs of pellets or 400 of corn/roasted soybean mix.It takes us around a year and a half to recoop our money on feed cost savings. Retail as of 2015 was $575 but if you have some people that want to go in with you,Jamie has a dealer program that if you buy 5 to 10 the cost is $442.
