Theres a few long double 10 ga percussion guns .
I wish my 8 ga muzzle loader was legal for duck and geese , would be interesting to see it used like it was in its day . Besides the 16lbs of mass it does shoulder quite well .
I may add some other sxs muzzleloaders to the collection in the future just so the 8 ga isnt lonely haha .
