I think those loads should cycle just fine. I have a Vinci, and it cycles everything I've ever put in it, including some pretty light loads. An m2 should have no problems as well. the crio chokes pattern pretty good, the improved cylinder or mod works well for doves and ducks. For turkey you may want to go to an aftermarket choke, depending on what ammo and what range you want to shoot. A 26" barrel m2 would be a very versatile gun that will provide years of enjoyment.
