I have a Carlson's Long Beard choke in my Winchester SX4 12 gauge. That gun uses the Browning Invector Plus system. It's a .665 choke constriction. I've tested it at 40 yards using Winchester Long Beard 3.5" #5. Here's what it will do (though I shot a wee bit high).

I have a Carlson's Turkey Choke, .665 constriction, in my Browning A5. The A5 uses the Browning Ivector DS choke tube system. With Long Bear 3.5" #5, this is that it will do.

Not much to choose from between the two guns.
