RE: What is the best turkey shell for a Mossberg 835
Winchester 2oz #5's in 3" is exactly what I shoot out of my Mossberg 835 with a Madd Maxx choke....I have no reason to go to 3.5" so...you'll probably do well with either you mentioned however I would still pattern them prior to going out this season.....
All shells shoot differently in all make/model guns and choke combinations....shoot a couple and they'll let you know...
