I have a boar about 600lbs.. I tried using a 300 gallon barrel with pig nipple to water him. I used 2 ratchet straps to strap it down,because he pushes it over without. He problem is that he broke 2 barrels by crushing them inward. I am now using a 175 gallon rubbermaid watered used by my cattle. What can I use other than the rubbermaid ,since it takes up to much room.
