I would recommend the federal Game Shok Metro Sub-Sonic Low Recoil loads. The muzzle velocity is 900 fps. However, these loads are worse than the 20 gauge. Another problem is that they come only in #7 1/2 shot. Also, you didn't specify which shell length you used. If you used 3" shells, I suggest using the 2 3/4" shells. If the 12 gauge is too much for you, that you have to take low recoil 12 gauge loads, I would suggest the 20 gauge. Why don't you ask your dad, bigbulls?
