I used ta could do 3 with a pump gun, thought I was good, never could get 4 unless it didn't break when it hit the ground. Thats why I never bough an auto loader, I eat up to many shells trying ta do better. There was some one, can't remember who back in the 50's and 60's could do 6 or 7 with a Model 12 Winchester, the old model with out the disconector.
