The NRMA offers a set of plans for a pretty good reloading bench. You can purchase them from their web site. If you do decide to build one, I strongly advise going with as heavy lumber as you can, i.e, 4X4 or 5X5 for the legs, 2X6 or ideally 3X5 for the top or laminate several layers of 3/4" plywood together. Longer and wider is better too! You'll find that no matter how big you build it, you can never have too much desktop space or storage space if you build a hutch to go with it. The extra weight and strength of the lumber makes for a really solid bench that won't move or flex, even when resizing the biggest cases.
