Best left to a trained gunsmith.
It can be, depending on the action the gun uses. It can also be illegal if you cut the barrel length below the legal limit. In the US, a Title 1 rifle must have a minimum barrel length of 16 inches, and a Title I shotgun must have a minimum barrel length of 18 inches.
You need to leave the barrel 16" or longer to be legal.
A shotgun is an example of a smoothbore. The inside of the barrel has no grooves cut into it, as a rifle would have.
Weight is what affects recoil. Cut the barrel, reduce the weight, recoil will increase if all else is equal.
Take it to a gunsmith- who will also know how long the barrel must be to be legal.
Well if you cut the barrel and start at the feet,it can be good as a blender.
find a replacement barrel and cut to the length you want
Shotgun barrels in the US must be at least 18 inches long, and are generally smooth inside. Handgun barrels are usually much shorter than 18 inches, and are rifled- a set of spiral grooves (rifling) is cut into the inside of the barrel to make bullets spin when fired.
It is a Savage/Stevens Model 94, and the barrel has been cut off. Value is minimal.
Under US Federal law, a shotgun not registered as an SBS must have a barrel at least 18 inches long, and an overall length of at least 26 inches. The barrel will need to be cut squarely, and the muzzle recrowned. This should NOT be attempted with a pipe cutter (it crimps the metal inwards) and is best performed by a gunsmith with a lathe. Would strongly suggest staying an inch above the minimums to allow for errors in measuring and finishing the metal.
A barrel with ports cut in it.
