Hi guys,
Im hoping this will help the next guy. I had read about the FX Impact having POI shifts but I didn't pay much attention to it. Thats where my story begins; I got my shiny new Impact a few weeks ago and began the wonderful journey to frustration. I was shooting good but not great the groups seemed to shift about an inch up, down to the left or right with no rhyme or reason. I thought is my scope moving...checked everything, I even put another scope on to see if that was it, NOPE. On to the next thing pellets, I tried several weights and brands with no luck. Next on to tuning lets see if that helps 800-950 in 10-15 fps increments-No love ..Hmmmmm its got to be in the gun..I called FX who were more that helpful with things to check (pellet probe going in smooth, chrono speeds and so on)SOOOOO here is what you have been waiting for......What was it...To be honest I did two things at the same time (1) I installed new o-rings in the 1/2 UNF adaptor at the end of the barrel. (2) I polished the barrel with diamond paste down to 3.5 micron. I was noticing my barrel was fouling within 300 or so shots. Im honestly not sure which one was the culprit but my guess is the barrel. Here is a picture of my target shot @48yards, the top row was while the barrel was seasoning back in. This is what I had hoped I could get out of this gun. Thats about as good as i can shoot to be honest. Pellet on pellet is probably not in my skill set at the moment.
I know how you guys want to see more than one group so here she is in all of its glory!!
Reg set at 100, JSB 18.1 @940 fps (yes I know thats smoking for the pellets but it works)
