The Prophet

Got it set up and everything was spot on. Went out the next morning and but it on the bench rest and shot at splatter burst at 50 Yds. I couldn't tell where I was hitting, although I hearde it, but the target had pretty well used up. Replaced that target and went after a fresh one. I couldn't believe I was hitting 8" low and 3" left. Now that I had a clean target I got on the turrets and moved things around until POI was same as POA. Decided to shoot a 4 shot group and see how it went. Shot 3 was again way off and to the different side this time. I had this happen before and sent my scope to Hawke and they returned a new one and said the one I sent in was defective. I took the scope off and started getting ready to mount a different one and a brain cell fired. This happened before with other rifles and cleaning the barrel cured it. It cured i here also. The strange thing is I did clean it when I got it and have only put maybe 2 tins of pellets through it. Different rifles are more sensitive to clean than others. What I am wondering is the Prophet one of those rifles that need regular barrell cleaning to keep it on target? Any one else chime in and describe what they have found.
