Thread: 20 GA for ducks

All gauges are appropriate for waterfowl over land and water.

You just need to match your choke and chosen load / factory ammunition to the distance you shoot.

The principal does not change - pattern the shotgun at the distances you plan to shoot and then place out range markers / stakes / decoys with a band etc at YOUR max effective range.

It matters not if you are shooting rabbits with a 17hmr, Reds with your 270 (god's calibre) or pigeons with target loads. Practice with the equipment, the ammunition, at the range you intend to shoot at to ensure you are ethical / effective.
