I've got the Sovereign racks w/35lbs. of lead shot per tier. The legs are easy to fill but the square tube framing is tricky. I made the mistake of using black duct tape to seal the holes. It was great for 3yrs and then the adhesive of one of the pieces on one of the top tiers melted off. Luckily for me, none of the shot made it into any of the components' vents. I'm going to try self-tapping screws to prevent it from happening again.
B.T.W., filling the frames is a must to prevent them from "ringing" - simply tap along the side of the frames w/your fingernail to hear what I mean. It amazes me that the designers of such a great rack never thought of this!
