Well, kshutt, guess we got some helpful advice, which is what we wanted to know, being new to turkey hunting. This will be my second year to hunt turkey and kshutt has been my mentor on many things about fire arms. I'm very disappointed in a response that brought in the ethical statement of any person shooting a turkey beyond 40yds, and said BS. I was there pattering my new Mossberg 835 by kshutt as my instructor on how to go about this process. I was not using Winchester LB ammo, I was using the Winchester supreme double load, 4shot, 1300vol. I was very impressed with the performance of the LB in kshutt's 835 using the Winchester LB. As I too was curious, just how far will it keep a tight pattern, so we did just that. Tested to see, I know that with the terrain kshutt and I will be hunting on, we can not shot beyond 40yrds. I also recall the conversation setting up at 45 yrds that I mentioned this is probably the max distance to shot a turkey because the pattern is spreading bigger and would ruin the meat and put too many pellets into the body. One other point to be made about shooting beyond 40 yrds, at kshutt's and my age, I don't know how his eyesight is, but it was getting difficult to place the egg shape head in the sights for me. So I don't see either of us taking a shot beyond 30yds do to a lot of different factors. Still fun testing out the new LB ammo and learning about pattering a turkey gun. That being said, those members with helpful advise, thanks, mentors are very appreciated because I would like to teach my son to turkey hunt, those members whom lurk to be negative, thanks to for teaching how not to be a future mentor for my nephews and my son. Kshutt, I hope somebody will help you on the choke diameter question, if not, after turkey season we shout pattern your 935 with different chokes, document it and share on here for others to maybe use for their questions or curiosity.
