I bought an 835 when they first came out. Back then they came with what they called their XX full turkey choke (which was hideous in regards to lousy patterns) and their regular full choke. The regular full choke that came with them shot an awesome pattern with Federal 3.5" 2 1/4 oz loads of 4 shot. I do not have any experience with what they come with now. My cuz had one too and he put a Madd Maxx .665 after market choke on his but to me it didn't shoot any better than the regular full choke did.
