I picked up some crio plus steel shot choke tubes from Carlson for my benelli M2.

Dammmmnn they pattern nice.

I've installed Carlson's tubes in many older shotguns and the customers rave about 'em.. Good to hear you like them too..

Did you buy the waterfowl 3 pack? I bought it for my sons gun a few years ago and they pattern just fine also. I doubt we will ever use the long range with steel shot.
