I have a question regarding the proper selection of a choke for shooting much larger sized buckshot. For example, whether it is Tri-Ball by Dixie Slugs, or ammo like Triple Hog Ball, which choke is going to give you the tightest pattern for between 30-50 yards? I have searched the internet and even called several choke manufacturers and have not been able to get a clear answer. I would be shooting a Mossberg 535 and it would be for deer hunting.
