Which of the Browning shot guns have the longer forcing ones ???

[fox fire]

I found some info about the Browning shotguns having a longer forcing cone (some of them anyway), I'm thinkin its called vector pro, vortex pro or something simalar, can anyone fill me in, I was interested in maybe finding one for a turkey gun.
                                       
                                                                                                                                          Thanx in advance

Browning's website is a great place to start

I heard once that the guns with the Invector Plus choke tube system had longer forcing cones and backbored barrels as opposed to the older Invector barrels. I think most if not all of the 12 guage guns come with the Invector Plus barrels now, but I'm not sure about the other guages. Check the website to verify this info because I have never researched this, it is just what I have been told.
