I'm new to Turkey Hunting. Last year, my first, I used a borrowed 12 gauge with a turkey choke.

This year it'll be my own equipment. My choices are:

1) The old 870 12 which was a Full but was bored out to Modified to shoot steel.

2) A 870 Express 20 with interchangeable chokes. I'd buy a turkey choke.

3) Buy a new 12 with interchangeable chokes.

Most of my hunting will be from ground blinds. After reading the 12 vs 20 thread I'm thinking I just use the 20 and get a good choke and some Heavishot. Any advice on my options?
