I have the whole set of little skeeters for a 12 gauge and they work OK except for the 410. I would think that the 410 in a 28 gauge gun would work OK but the 410 in a 12ga is pretty worthless. I have tried even using a full choke in the 12ga but it still is difficult to break a skeet target with it. The 28, and 20 in a 12ga work pretty good. You do need something to help knock out the empty shell (like a number 2 pencil).
So how do these work? It looks like you just plop a shell into it and load them into the barrel . Then after firing they eject or extract and you pull out fired rounds and replace with unfired Is that correct? If so I’m thinking I will stick to my 3/4 oz. 12 ga. reloads.
they stay in place with rubber bushings up front to keep it snug. then you tap them in flush with the breech face and a slave unit operates the ejectors.
I'm little confused. Why is, or even how, is a No. 2 pencil used or needed ? Don't the extractors/ejectors work with th sub gauge tubes ?
