How much would a supernova rifled barrel cost, and where could I get one? Also are these hard to come across, and can I order it straight from benelli? I guess if the price is too high I guess I can settle w a rifled choke but I am lost to as which one to get. It is hard for me to make a trip to cabelas, dicks or gander mountain cause I live in a small town away from everything except walmart:). So i guess my final question would be as to what rifled choke I should get, and what choke is best for regular slugs as well? Thanks.
