Here's my 20 gauge 1.625 ozs. of #9 tungsten super shot at 40 yards at just under 1200 fps. .570 choke. That's a 10" circle with 279 shot holes. There are 342 tungsten 9s in 1 oz. For comparison, there are 585 lead 9s in an oz. The tungsten is almost twice as dense as lead. This load is hell on turkeys.
