Put a couple of box’s of 3 inch through it. If you’ve already put a few through and it’s not cycling them, take a look at the bolt carrier.
Pull it down and the chassis the bolt moves with needs a little filing. There’s a square shoulder on the butt end. Just needs to be rounded abit. Search utube Stoeger. A few pop up and one of them explains and shows how to do it. There’s also a few other tips and tricks there as well
Also keep an eye on where the bolt locks into the chamber.
Im not saying the 3000 will do this, but my 2000 did. Had quite few through it, mainly 3 “ but ruined a days shooting
