I just bought another Remmington Model 870 Magnum. I have the classic woodgrain already and now I got an all black synthetic model that I am gonna turn into a home defense weapon with all the goodies. It came with a 20 inch rifled barrel, Since I want to shoot 00 buck I purchased a 20 inch smooth bore barrel. Now here is my question, what would happen if I shot 00 buch threw a rifled barrel? I know that your not supposed too but I was wondering what the result would be?
