I don't think there is a difference between the Prohunter and Encore and if so, no. My Encore frame started out as a pistol...15 inchin30-06. I also have a .223 rifle barrel for it and a 209x50 front stuffer for it. Change back and forth at will. IfNY decides to let my county partake in the rifle option for deer, I am probably going to get a 25-06 or 280 Rem. rifle barrel for it.
