martin from leeds i have a 1100 12g remy hushpower it cycles 32g subsonics perfect you can use normal 28s but it will only cycle once because it is tuned to susonic.i have got a spare barrel.but once you fire it a few times you get used to it.the front end is a bit on the heavy side because of the moderator.as for noise it is still a bit loud for shooting around property i would be a bit carefull.
