Xpert steel is not your "Best" choice. You can kill birds with them. usually don't pattern well. You really do get what you pay for. For the price you should check out Kent faststeel. That is all I use and it works great for me. As for your turkey choke... You should use a Modified. Full at most. It will help your odds of killing birds! I assume you are hunting geese. BB's and#2's is what I shoot. ducks I always shoot 2 3/4" #4's. Good luck!
