Based on a couple of comments here it may be that there is some misconseption as to how powerful the typical 20 ga sabot load is. On average they throw a 260 grain bullet at somewhere between 1600 and 1900 FPS. In essence not much different than a very hot .44 magnum out of a levergun.

Of course what someone with a reloader and those brass cases and full sized bullets (62 cal)might come up with is another thing. Which brings me back to thinking about shooting a load such as that out of a 6 3/4 pound gun!!!!!
