I've hunted with my 1300 short turkey for the last 8 years, and took a lot of birds. It has a x-long x-full winchester choke and it's great! I have taken several birds at 50-55yds no problem, and I shoot hevi13's! Wouldn't think of changing chokes. That being said, I lost my front sight and am using my I-12 this season. I bought a tru-glo gobble stopper, and peppered a bird at 50 yards opening day and he flew off! I've taken 3 since, but the farthest was 30yds. Should have spent the money on a better choke!
