Well the new stainless barrel shot the first loading I put together for it right at an inch for three shots. A bit mild 80 grains by volume Jim Shockey's 3F gold under a Harvester crush rib sabot holding a Speer 240 grain Unicor, After some hunting I was able to trade some large rifle primers for shotshell primers so I will be good for a while. One of the screw holes in the base is stripped out so I am going to have it tapped for a 6 hole base so testing heavy loads won't be an issue.
