FX FX Impact M3 700mm barrel 18.13 grain .22 jsb pellets STX Liner 62 yards 18 shots unsorted

If youi sort the pellets by weight, then your group size should be cut in half. Also, I would test this at different velocities. 960 is rather hot. I would start at 880, shoot a 10 shot group, then repeat after increasing velocity 10 fps.

Excellent groups there Bhaur, nice video! I shoot the 18gr @ 970 thru my RAW, it's barrel likes speed.

I see that Polygonal barrels prefer fast speed. FX barrel is also some kind of soft groove barrel similar to Polygonal.
We have seen that FX Impact doesn't follow the rule of fps from 850 to 920 for extreme accuracy. Rather these barrels become extremely accurate when they run apparently hot like 940fps to 970fps with 18.13 grain .22 jsb.

Well, I was shooting at 968 and I saw they were very accurate. So I decided to follow a few guys from YouTube with there settings but don’t had the same results. So I believe like you said, they need between 940 and 970fps. Good job!

Solid group there. I tried 950 in my Crown with 700mm. They shot well to 75 yards. At 100 they were like a curve ball.

I don’t understand your question. I didn’t change settings at 100. I put my 700mm barrel on my crown and gave it a loose tune at 950ish fps with 18.13’s. They shot well up to 75 yards. When i shot them at 100 yards they were all over the place.
