They are both capable out to 200 yards. I have an original Encore and have been thinking over the new ProHunter. The Prohunter is the improved version of the original Encore. The stock, barrel, swing hammer, and breech plug have all been improved.
It's a tough call with the season fastly approaching. I called a gun shop in the Albany, NY area the other day and they had quite a few in stock, which surprised me. I would either try to locate a ProHunter elsewhere or wait to get the one you have ordered. You're most likely going to be shooting 150 grains of powder, the new stock helps cut down on the recoil.
I'm in the opposite situation as you. I've located a ProHunter in stock, I just have been able to get the clearance from the wife!!!![:@]
Hope you find one. If you decide to go with a regular Encore you'll save a little money. The original Encores are great guns, either way you'll be happy with it.
