The "more payload equals better patterns" logic makes sense, but is often not the case. A 3.5" long shot column in the barrel is alot of pellets getting deformed, and 3.5" patterns may not equal traditional 3" ones. It will take shooting to tell, and you will notice that.
As an example, I have some 3" shells that throw tighter patterns with 1-3/4 oz of shot, than shells with heavier payloads, , and often the 1-3/4 loads will yield denser patterns with a shot size heavier, ie, 1-3/4 oz of #5 will pattern better than 1-7/8 or 2 oz of #6. The 1-3/4 oz loads are faster too, which are a component of killing power and reach.
I suspect we have about reached the limit of useful payload in the 12 ga at 2 oz of shot. No proof of that, just an opinion. Moving up to 10 ga makes for a shorter shot stack ( did I just invent that phrase?) and maybe over 2 oz of shot work better in the 10 ga, I dunno. The 835 is back bored to 10 ga dia, but the 3.5" 12 ga shell still has the longer stack. And 10 ga guns are not really that portable for ridge running gobblers.
