12g double barrel percussion shotgun

[TRex87]

I have a Pedersoli double 12 ga. I made a rear aperture sight that slips into the tang screw to help me get my alignment correct. I've only shot round ball in the left barrel with a cylinder choke tube screwed in. It shoots about 3" left at 25 yards and about 6" left at 50 yards. I haven't really grouped it. But if I hold on the right edge of my 12" steel plate at 50 yards, I'll smack it most of the time. That's with only about 75 grains of 2F, a cushion wad, ball & card to top it off. I think of it as a black powder version of a bow -- good enough for anything I may encounter from quail up to large bear. But only at close ranges.

In many states, including my own, dedicated muzzleloader seasons are only allowed to have a single barrel. It's fine to use a double barrel during the general season though. Just check your regs before heading afield.

Good point about single shot for ML season

Has anyone on here had luck w a double barrel & round ball?

I kinda assumed they shot like a smoothbore musket, after hearing some claim similar groups at 50yd…like 3-4”

Anyone made it work consistently?

My old 20 ga double would shoot RBs into a 50 yard group sized 3" to 4" virtually every time. But, ONLY from the right barrel! (it was not choked)
The left side was choked mod/full and would never shoot RBs very well with any load I tried, 6" to 12" was the usual group.
They both were regulated to close to the same POI, but the muzzle constriction only worked well for small-sized shot.
