Quit buying dove loads by price ! I would recomend Winchester2 3/4 " AA target loads with #8 shot or Rem,Fed. The good target loads are loaded with hard shot and good wads for better paterening . I know they cost more but you should be able to sell the AA hulls for 3-5 cents each and you will have to shoot fewer shots. What choke are you using ? I use a Mod in my 20 for dove.
