I can pick up a Benelli Vinci for about $200 or so cheaper than a Benelli Super Vinci and the Vinci can be had with a 24 inch barrel while the SV comes in shortest 26 inch barrel. For turkey, fox, coyote, rabbit, duck, dove how much more range could I get with a 3.5 inch gun?
Range is more a factor of shot size than case length..
I've never seen the need for anything over a 2 3/4" chamber yet..
