I'm currently at 925fps on current tune with a 22 WC mk1 ST but haven't had a chance to test for accuracy at current speed. How fast are you shooting the 18g Jsb's out of your smooth twist barrel without loss of accuracy?

iv shots those speeds out of my impact when I had it and it was very good put it on paper see how it is then slow it down a little and compare but 925 I think your in the ballpark with the newer x barrels seems you can up the speeds some. I remember when 860 -880 was fast I think ted did a video on this also my uragan is shooting 16 gr at 900 very accurate

The FX MK1 ST with the solid rigid barrels seem to be more forgiving when shooting JSBs and their variants at higher speeds up to 975fps actually up to 1050fps from what I noticed in my MK1 Bobcats and Royales. YO!

i own a few ST fx guns anf they both accurate at 920fps , beyond this grroups open up. I do have to say mine at 860 to 870 isa bit more accurate . but if you need the extra power ,
