I gave you some choke/shot size selection examples in the other post.But I didn't give you any name brands.The combo's my friends have used with the best results at50+ydsare.The kicks .685 with 3.5" Winchester HV #4's,and a Star-dot with the same shell.#4's will reach out farther than 40-50.If you only want to shoot 40-50 I would try the kicks .680,and 3.5" WIn HV #5's.This is my friends first bird I called in for him.He shot it with his 835 at 52yds with the 3.5" Winchester HV #4's,and a Star-dot choke.Dropped him in his tracks.I came up with this choke/load combo for him,and you can see he's very satisfied!IMO Star-dot's and Kicks are 2 of the best choke brands,and 3.5"Winchester HV shells are awesome!Just my opinion.
