In my opinion, Kirk Merrington probably taught the Briley people about shotgun sleeving when he worked there. He has been gone from Briley a long time. I don't believe Briley gets enough practice to keep their quality of sleeving up to par. I'm not sure that Briley doesn't send some (or all) of the sleeving work to Merrington for the basic sleeving and then finish it up in their shop.
