welp, ive decided to dish out the cash to go hevi... I dont know whether i will try the fed hw's or the hevi-13's but either way i gotta get a new choke tube for the supernova.. any suggestions? I dont know much about hevi-weight loads or how they pattern but i could use some advice on what choke tube i should purchase.. i keep seeing these patterns with 400+ in a 10-20 inch cirlce.. I WANT THAT! haha can anyone give me some info?
