Swapping smoothbore & rifle barrels
I bought a cantilevered rifle barrel for my Mossberg 500 20 gauge shotgun. I mounted a scope on it and sighted it in. However, I still want to use the gun's original smooth bore barrel for small game hunting. Will swapping the barrels back and forth affect the accuracy of the scope? In other words, will I have to re-sight the rifle barrel every time I want to use ?
