Listen up guys. Just talked with a real skeet shooting champion, Luke DesHotels ( email@example.com
Luke has a history a mile long for many wins, plus is in the hall of fame. Happened to talk to him as he has a 28" Tula Choked Barrel for sale. He is a pretty busy guy and has a noted shooting facility in the Atlanta, GA area. If your looking for a barrel at a great price send him a note. If you have the time check Luke out on the NSSA.
Second, found a solution to my problem. Birchwood Casey makes a product called, "Lead Remover and Polishing Cloth". I purchased some of this and cut it into cleaning patch size pieces. Wrapped these pieces around a 10ga cleaning brush which I chucked up in my hand drill. After cleaning the choke out good I then inserted the brush etc. and polished the inide of the choke keeping the drill moving in and out. It did a great job in cleaning out the choke. Hope this may be of help if needed. Got the cloth at Gander Mtn. for $4.99.
