My 11-87 is the turkey model, with the shurshot stock, 23" barrel, and shoots 3.5" shells. The gun has a rear and front adjustable sights that are similar to rifle sights. Currently I am shooting 3.5" Nitros with a Jellyhead choke that the owner of Nitro recommend I try. I've killed four turkeys with this combination, and I've hit every single one of them low and to the left. The Nitros are absolutely the most destructive shell I've ever shot a turkey with but my problem is that the majority of my pellets are hitting the body of the turkey. In two of the last four kills, it has practically ruined the breast. I believe part of my problem is that I'm naturally aiming a little low because of a fear of shooting over the turkey.
My question is: do I need to continue to try and adjust the sights I have now? Try to consciously make myself aim higher? Try another load of shells? Try one of these holographic sights like a Burris speed dot or an EOTech?
My confidence is high in my shell/choke combination right now because of killing a few turkeys with it. I just want the turkey's head to be bloodier instead of his breast.
