Thanks Mike, and you're probably right about too much sugar for a dime....and I've never heard that one before, good one! I finally thought to just look at the boxes of old 16 bore ammo I have. You're right I believe, 1 oz. is probably the classic load for a 16. I do have two boxes of Remington 1 1/8 oz. loads. I also noticed that 2 1/2 drams was the most common with 2 3/4 drams for the 1 1/8 oz. load.
I did hit a glitch...maybe. While double checking my measurements I stuck the calipers in the muzzle. It mics .640-.642, I guess I forgot that. That's gonna squeeze the .678 RB down .036. Is shooting a RB with that much constriction a good practice? Bear in mind I'm 95% a rifleman and not near as comfortable working with smootbores. If my memory serves me correctly with that much constriction I shouldn't expect much in the way of accuracy. But then, I wonder how much difference there is between a round ball hitting 3-4 inches of rifling at the end of a barrel as in the Paradox and Explora firearms and hitting that much choke?
I did try two 1 oz. loads and two 1 1/8 oz. loads of #6 shot. 1 oz. load was 2 1/2 drams and 1 1/8 oz. load was 2 3/4 drams. Pattern looked pretty fair from about 30 yards on a white board and recoil was mild, hulls fell from the chamber when the barrels were turned up.
Oh the burdens I carry....being compelled to work with these old things.
