It was shooting 25.4 grain FX .22 pellets at 965 FPS when I received it. I didn’t fool with the tune at all because I was getting sub 1/2” groups at 50 yards.
Over the past few weeks I have put 2500 pellets through it and it has settled in at 941 FPS with .375 “ groups not uncommon.
Attached is a 45 shot string I shot a couple of days ago. Average FPS 941, extreme spread 8, standard deviation 2. I don’t think it gets much better than that!
The rifle and I are going to Phoenix and shoot the Extreme Benchrest event. I hope you see my name at the top of the results list.
Thanks,

I won the Extreme Benchrest Speed Silhouette (Sportsman division) with the FX Impact you sold me! I sported your brand at the finals.
