Steve,

Do you shoot the hollow base bullet, and, if so, with or without a plug? If plugged, with what? Total projectile weight? Powder and load?

You may recall that I had a Smith, London, Jones action double for this round years ago. I never shot it, but Kearcher had worked up a nice smokeless load for it - it went down the road in trade for an eight bore Reilly. However, I still have a little single shot like yours, and dream of using it on our Oregon elk.
