I recently ordered a set of 12-20 Seminole Chambermates from Seminole Gunworks. I ordered them on a Monday, and received them on Wednesday of the same week. I was happy to see they shipped them the same day I ordered them.
The package included two 12-20 Chambermates, one bag of standard size o-rings, one bag of oversized o-rings, a small tub of lube, a Chambermates extraction tool, and a plastic carrying case.
The reason they include two different size o-rings is the 12-20 Chambermates are a universal fit. Meaning they will work in virtually any 12ga O/U or SxS shotgun. The different size o-rings are used to adjust for different size chambers.
After carefully reading the instructions (OK, my friend Tim read them) I installed the Chambermates with the standard size o-rings. You simply smear a little lube on the o-ring, and insert the Chambermates as you would any 12ga shell.
The instructions say to use quality shells like AA's or STS's, so of course I wanted to see how they'd work with Estates.
There are reports that the cheaper shells may cause extraction problems. They may swell in the Chambermate and pull it out with the extractor.
I fired about a box of the Estates, and did have some problems. Rather than switch to more expensive shells, I just changed to the oversized o-rings, and that took care of the extraction problems.
After that I didn't experience any other issues. The Chambermates worked flawlessly, and reset the triggers on my Browning 525 without any problem.
We conducted some informal patterning tests and they passed with flying colors. I would have no problem recommending them to anybody else.
Now I can shoot 20ga events without dragging an extra gun around with me.
P.S. I've got a 20ga Browning 425 for sale, if you know anybody.
