I've deer hunted successfully over the past few years and although i've gone out for turkey once i had no luck.
I am debating on using my 20 gauge shotgun or my 22 mag. I have been doing some scouting and decided on using my blind in a place that will give me a 30 yard shot at most.

My questions are:

1. If i decide on the 20g will 30 yards be too far with a full choke? (the full is what came with the Moss 500)

2. If i decide on the 22mag where would i shoot the bird? I would be using a scoped gun off of shooting sticks in my blind.
