A Mossberg 352KC has recently come to live with me. It has a magazine the is supposed to hold 7 rounds, but I can only get 5 rounds in it. I cannot find anything online about how to repair one of these. Any help would be appreciated.
As a side note this magazine (and gun) will shoot .22 Short, Long & Long Rifle. What (if any) reason is there to get .22S ammo?
