RE: old encore to new prohunter?
You can get a blued & fluted barrel from Bergara for the encore. I don't think they make them with the speed breech quite like TC. They also do not come with the tip over primer extractor either (which on my Pro Hunter rarely works).
I do not believe TC makes a fluted & blued barrel for the encore. I would call Fox Ridge Outfitters (1-800-243-4570) and check with them. Maybe the Custom Shop at TC would make it.
