I purchased a Posten Woodsman from Jim about 3 weeks ago and after shooting it it didn't seem to help me as far as steadying my pins. So I had a friend of mine who owns a machine shop fabricate me a 3 inch diameter piece of stainless 1/4 inch thick which weighs in at 8 ounces exactly. I removed the 2 weights from my Woodsman and attached the SS disk with the screw in end cap that came with the Posten and viola much tighter groups at 40 and 50 yards. You guys out there who own a Posten owe it to yourself to give this a try. I feel I now have the best of both worlds in one very adjustable stab.
