I just purchased a remington 3200 and the beads do not figure eight, I see thr rib in between. I tried shooting some targets not hitting very many. Took it to shoot a patern and found all but a few pellets hit above the center but a really even pattern. That was the result with both barrels. Now my question. Will it help me to put a higher rib and add an adjustable comb? Any help would be appreciated. I really like the gun and would hate to think I just blew a bunch of money.
