For geese I shoot reloaded 1 3/8 oz of Hevi Shot # 2 or 3 at 1500 fps

For ducks I shoot either 1 1/4 oz of Hevi Shot # 6 at 1500 fps or a reload of 1 oz of #3 steel at 1550

If the geese are decoying Hevi Shot is not needed Steel BB will do .
If they flair at 40 or so yards the steel BB are maxed out but the Hevi #2 or 3 will kill them cleanly to 60+ yds

Decoying ducks only need my steel #3 but pass shooting the Hevi #6 realy shines
