I use a 55gal drum with the end cut out, and chained to a tree. I put a heavy steel band around the drum at the top with eyes to attatch chains. I then suspend the drum from two trees so it will only tilt to about 15 degrees. This slows the bears down, and they don't empty it so fast. I load it with dog food, then pour 1 gal of pancake syrup over the dog food. I mix 1 package rasberry jello in 5 gal of water. I hang the bucket of jello water in the tree above the drum. I tie an old towel to the suspension rope, then let it hang to the bottom of the bucket. the towel acts as a wick to get the rasberry smell out on the wind.
I use a .350 Rem Mag, or a .35 Whelen, in the stand. My son uses a 45-70. I also carry my recurve bow with blunts to run off the sows, and small bears.
