I bought my Pro Hunter a couple weeks ago. Saturday I was with a very good friend of mine who shoots a KP1. We were getting dialed in for gun season opening here in Ohio. He put a few rounds through my Pro Hunter, I put a few rounds through his KP1. I am using 90gr. BH209, he is using 100gr. 777 pellets, both using Win. 209 Primers. I am using Hornaday 240 XTG through thePro Hunter,he is using 250 gr. SST through the KP1. We both kept our respective bullets and sabots. I was glad to hand his KP1 back to him after shooting it. Long story short, this afternoon we dialed in his brand new Stainless ProHunterthat he traded his KP1 in for on Sunday. The Pro Hunter is my first muzzleloader and the first gun I've ever owned with that muchrecoil, but the KP1 just plain hurt. It's amazing what that limbsaver pad along with the flextech stock can do. I made a good decision on my Pro Hunter, it may not be the cheapest, but I am very happy with it. When he told me he traded up I asked him why, his answer was, the Pro Hunter shouldered much better, almost like it was designed for my shoulder. I really like that there is no blowback and everything is contained in the barrel, and lastly the felt recoil was much lower with the Pro Hunter. Good luck with your choice.
