Anyone else had this issue ?
Subsonics not cycling in a moderated semi auto shotgun

Why were you expecting them too?
Most auto shotguns either need enough gas to cycle or inertia depending on mechanism.
If however your gun was cycling and has now stopped remove all oils and greases from the complete action. It simply likes to mix with combustion materials to make a sticky tar.

Cycles normal cartridges fine was just trying to make it a bit quieter so bought a box to try and stupidly thought as 32g would be fine
Yes. 2 Keepers I know own Ruger 10/22's. The only reliable ammo to cycle the action is CCI subsonic 40gr. They have tried Winchester, Ely, Remington with mixed results.
Eley is the quietest. CCI does give the occasional crack.
it does rely on how clean the rifle action is.

I’m using cci just now and am working through a batch that are not subsonic. Bloody loud things
These are 12g not rifle ammo , just checked they are actually 28 grams not 32s
It's a beretta a303 with a hushpower mod and game bore evo Rs
Im not as familiar with berettas as other makes, but I have had some of my gas and inertia guns not cycle low loads (and one with some subsonics) until I had them broken in with really heavy stuff, if its a 3" chamber I would recommend a box or even two of 50g BB just to see if that changes anything.
I had a SBE3 and an SX4 (so inertia and gas) which had issues cycling lower clay and game loads (28-30g) and the BB treatment worked a treat.

Why are you surprised ?
There’s a reason hushpowers are generally break action or pump action shotguns.
Didn't give it much thought
Unfortunately you’re no going to get subs to cycle properly so it a fully moderated single shot or partially moderated semi

Any semi automatic needs a certain level of recoil, inertia or gas pressure required to cycle the action. Subsonic cartridges need much less gas energy to accelerate the load to subsonic velocities and produce much less recoil. Most semi’s struggle with light recoiling loads.
Its the reason why most American police shotguns are pump actions - they use low recoiling bean bag and less than lethal ammunition as well as full power shot and slugs. A pump handles any ammunition regardless of the level of recoil.

Apologies. Shotgun not Rifle. RTFQ!

I have an old beat up Baikal hush power about a half mile long.
It's ugly but I shoot it really well. The length actually helps. And although not silent I have noticed that birds are soon to be coming in again. Any supersonic crack that is present seems to have little range, especially when windy.
