Browning gti 123

I'm looking for recommendations for quietest cartridges to use in my 20g mossberg hushpower for pigeons. I would normally use a 12g but houses are in very close proximity so looking for quiet as possible. Not keen on game bore hushpower cartridges any other recommendations would be much appreciated. Thanks
