So I'm getting ready to order a couple of the Sinclair chamber length gauges and thought I should order something else so I'm not paying shipping on such an itty bitty piece. I'm anal that way I guess. Anywho, I thought I'd pose the question as to what was or is the one little or maybe not so little gadget that is on your loading bench that you have gotten more use out of then you ever thought you would or the one thing that you're really glad you bought! Lets try to keep it below a 50 dollar bill if possible. And go!!
