Gibbs style black powder rifle

[Old Painless]

This Gibbs style rifle made by CVA has a octagon to round barrel. The muzzle looks like it has a more coned breach, if thats the proper word for it on a BP gun.
Is this how it was from the maker or done afterword? Or do coned jobs look to have more metal removed than this?
I think some of you do this to your guns.
Thanks, Robert

The breach is the “rear end” of the barrel. That is the muzzle crown that you are referring to. It is normal and most all muzzleloaders have the same type of crown. It came from the factory that way. Coning would involve removing more metal and further down the bore. I’ve owned or own two dozen muzzleloading rifles and never found the need to cone a muzzle.
