Any recommendations regarding optimal velocity for the Impact X smooth twist X barrel, using .22 cal, JSB 25.4 gr monsters. Currently, I'm getting no discernible grouping at 820-845 FPS at 55 yards. Groups at 40 yards are acceptable with an occasional flyer -- every 15 shots or so, even after sorting by weight.
I would like to get this .22 cal to shoot from 37-40fpe. Is this expecting too much?
Should I simply use the 18.1 gr JSB? If so, 870-900 fps?
Thanks in advance for any suggestions.
