I have the Maxus 3.5 All Purpose infinity camo version that is drilled and tapped with 26 inch barrel. It is the best patterning shotgun I have ever owned! Without any real workup, I bought a Hevi13 choke from Clark(as per his advice) and shot some Hevi 3.5 inch #6's that I had as well as #7's. I got about 240 with the #6's and around 280-300 with the #7's if I recall correctly with a real even pattern. I didnt find a need to test further after the results I got.
I like using the 6's as a good compromise of of size and power and with the numbers I got I dont feel a need to change anything. The gun is light and handles perfectly, and I even shot a few rounds of trap with it and smoked the clays shooting as well as I do with my Beretta 682.
Its soft shooting, points and shoulders great and is a dream to carry. I have or have had every major player in shotguns and this is my favorite for turkey so far.
