So, the 12 ga adapter arrived and I am very impressed with the product.
It’s fit to chamber is perfect and it has a recessed O-ring seal.
The cut-out fits where the extractor is, so it can’t pull it from the chamber when you open the action.
It’s to be used in my brothers single shot 12 ga with about 75-85 grains (volume) of RS Pyrodex and the same volume of shot. In our case, #6 is on hand. A #209 shotgun primer lights it off.
I liked it enough to order two of the 20 ga adapters to use in my Browning BSS 20 ga.
If it groups well @ 20-30 yards, it will get the call for turkeys this year.
