    You can jug choke it if you first remove the chrome with a hone but that would be a job in its self!!!!

    That is what I was worried about. I would rather have a modfied jug choke than have it threaded for tubes. I'll keep working at it, and hopefully I can make the cylinder bores work for me.

    Conditions were not good today. 20mph winds with strong gusts, as well as a light rain. Today I tried Fg Goex, and while patterns seem unchanged from Fg Swiss, the recoil felt less brutal. Maybe it was just me paying more attention to the wind. The same 2 ounce load with 1 nitro card only did 68 pellets, although the wind likely did not help. More importantly I tried the same load with a 12 gauge 1/2" fiber wad soaked in olive oil on top, the skycheif load. It turns out after soaking for a few weeks that they grow to nearly 11 gauge size. This did only 65 pellets, identical to only an overshot card.

    I tried some #4 lead shot, both an OS and skycheif loads, and they did 50 and 52 pellets. That's clearly no good. For the life of me, I could not find my #6 shot, but I did find my #5 bismuth. On a scale, I weighted 2 ounces, which should have nearly the same pellet count as 1 3/4 ounce of #6 lead. This did 65 pellets.

    I'm beginning to think #5 lead shot will not get me to 25 yards. I even tried nickel plated #5 with not a single bit of change. And #4 is going in the wrong direction. I am going to turn my focus over to #6, which is as small as I feel comfortable using.

    Not sure if you have seen this or not but I have to think it is safe for your modern made 10 ga.:

    http://www.tbullock.com/bpsg.html
    https://www.trackofthewolf.com/Categ...191/1/WAD-10-A

    Both for BP shotshells but I'd have to think safe for muzzleloader too.

    Here is some info specifically for muzzleloading shotguns:

    http://home.insightbb.com/~bspen/starr.html

    About half way down the page he talks about "lighter" guns and using 4 1/4 drams of BP under 1 1/2 oz. shot.

    Hopefully there is something useful there.

    The 2020 issue of Hodgdon's reloading Annual magazine has a article about using Old Eynsford black powder in some shotguns. He used a 10 gauge shotgun too. He published some reloading data for the 10 gauge and some other smaller ones too. Anyway maybe it might help you out.

    It is strange, but it seems Pedersoli does not come out and say a maximum. Just vague recommendations. I've resolved to keep things reasonable, say 2 1/4 ounce. The gun is light, but the barrels are every bit as stout as a modern 10 gauge. I trust it can handle non-stop 11,000 psi loads with out breaking a sweat. I would be surprised if these blackpowder loads are anywhere near that.

    Last night we got hit by the snow storm. I woke up to 3" of snow, with about 1" of slush underneath. I went to the range anyway. I am happy to say I found a true 25 yard load. Again I was working with Fg Goex, although this time I had #6 shot with. I started with #5 and again found loads to be about the same as Fg Swiss. When I switched to #6, it almost looked like the center of the pattern was thinner, even though I did not see that with #5. I tried a few combo's, including plastic wads, but no cure. To this point, the great majority of my loads were topped with a single overshot card punched from a cereal box. Finally I decided to try something stupid simple. The load was 100 gr powder, nitro card, 2 ounces #6 shot, and a nitro card for an overshot. This was the magic combo. Pellet count jumped right up to 102 in a 10" circle at 25 yards. Thinking it may be a fluke, I loaded again, and the second shot went 100. To this point I had only been shooting the left barrel, so I decided to try the right barrel. For fouling control I had been wetting the nitro cards in my mouth, the nitro card for using overshot was well saturated by the time I used it. For the right barrel I used dry wads. This went 92 pellets, which is adequate. I tried a second shot with soaked wads, and got 100. So it seems a lubed nitro card is the best overshot card. How's that for some load development!

    I still have a little more work to do. One of my ideas was a custom wad, but I forgot it at home. The idea was to use an unslit LBC50 wad, which is a 12 gauge wad that is a full .730" diameter. This obviously is a loose fit in my bore, but not as bad as one would think. The important thing was that I had punched some 10 gauge wads from 3/4" thick wool blocks I had found in some packaging, and glued to the bottom of the wad. Besides providing a gas seal, I'm hoping the wool will provide enough drag to keep the wad flying straight until the shot is released. I used the LBC50 wad for two reasons. One, I do not have an unslit 10 gauge wad. Two, I'm wondering if it may provide some kind of choking effect. During firing the shot will set back, and expand the wad to bore diameter. The question is will the wad then shrink back down upon exit and provide a choke, and more importantly will it release the shot.

    Besides that, I also want to try the skycheif load again with #6 shot. I did try varying the powder charge today, but I did not mess with the shot. I'll try some 1 3/4 and 2 1/4 ounce loads as well.
