The frames are not registered at all. In fact you can purchased them seperately without a pistol, rifle or muzzleloader barrel. All encores are interchangeable as far as barrels and stocks are concerned. As mentioned before, it is illegal to use a rifle buttstock and a barrel less than 18" in length on the same frame. It is printed on the end of all rifle buttstocks. The Prohunter is just a newer version of the encore.
The reason I asked is I see there are a few more options in barrel selection for the pro hunter. One more off topic question, do you think a 28" barrel wouldshoot better than a 24" barrel? in .243cal.
Bandhunter is correct 100%
glockman55,
You will gain a few more FPS on the 4inch longer barrel, nothing worth buying another barrel if you already have a 24inch. The accuracy wouldn't be much if any, it could be worst. The 243 is designed for a 24-26 barrel for the best proformance. Now that doesn't mean a good tweaked handload in the right length barrel may not shoot better , by no means. The extra 4 inches on the barrel would be a hinderance to me in my hunting situations, but maybe not yours? Hope this helps.
