shorten my barrel

[musketman]

With all due respect, why is it that a 30 inch barrel on a modern shotgun is considered " Long ", but on a muzzle loading shotgun, it is called " Too short???"

Because of the 6" or so for the receiver on a pump or semi. My Ithaca/SKB SXS has one set of 25" barrels and it looks like a sawed off coach gun. It's all about the balance.

That, and modern shotguns use smokeless powders that yeild higher pressures, so a long barrel is not needed when you are pushing shot with nitro...
