Ruth... The factory Mossberg sights do not give much adjustment. If I am correct, it is a piece of sheet metal snapped over the rib on the barrel. With 3 settings of adjustment, center ,right and left.
I replaced the factory sights with better Tru-Glo sights on my 835. But you said you have elevation and windage, That don't sound like the cheap factory set up.
There should be some screws on the sight to adjust it.
As far as aiming...I always aim when I shoot at turkeys.
Aim right for the waddles.
When wingshooting I would point the shotgun. The chokes for each task do different jobs. The turkey choke concentrates the shot, thats why you want to aim. Where as the modified and improved tubes spread out the shot more whereas pointing would work to hit your target.
Hope this helps.
