RE: Choke suggestions please!
 

I'd love to do the nitro thing too, but if I were you, I'd check out the stock choke first. Never know, it might be a winner out of the box.

RE: Choke suggestions please!
 

Do yourself a favor, try yourstock choke first with any buffered shot shell of your choice #5's or #6's. Don't go with Turkey full or Super Turkey Full chokes, cause you'll rip your birds in 1/2. That's to say you don't always shoot your birds 30+ yards out all the time! And if you do, I would go down 1 shot size to #4's & #5's (Buffered). Buffering is key, it prevents your pellets from deforming as they are moving down the barrel, hence tighter patterns with a lot less flyers. I would stick to full if you hunt field edges, and in woods Imp. Modified.
