What do you mean when you say "shot cup"?Interesting .... Following . Like Numb said ...long barreled doesn't mean heavy but they can be a pain in brushy areas . Last 42" Carolina Gun I made was 5 1/2 pds. . I like the handy ness of the shorter guns but I'd never take one under 40" turkey hunting . Its a pain getting a good tight group from a 42" barreled gun , why handicap your yourself on purpose ? Shot cups are helpful for tightening up groups ....
