I am new to the airgun world and I am looking into benchrest and then possibly PMC/PRS. I am pulling my hair out trying to decide on a proper gun. I keep going back and forth between the FX Impact M4 and the Skout Evo. Adding in more complexity is caliber..... From what I have seen looking at NAC and RMAC, .30 cal is the popular choice, but I have also seen good results with .22. I seek the wisdom and advice of those with MUCH more experience that I have to your recommendations. I am not going to be using this for hunting, just target/competition.
