I don't have the MKll Wildcat, just the original WC but I chronographed it when I first got it from Utah Airguns and it was shooting right at 895 to 900 fps with a spread of 12. It was a very accurate rifle ... literally a hole on hole rifle.
I have the gun in the shop at FXUSA right now getting them to check out the regulator, but I made a shot string just before sending it to Wilmington and this was the results shooting the 25.39 grain JSBs

I threw out the first two shots because they were so far off when considering the extreme spread but the stats for the string with those two shots removed was
Hi 873 / Lo 832 / Avg 854 / ES 41 / SD 10
Out of all 38 shots that I counted there were 5 in the 830s, 8 in the 840s, 13 in the 850s, 9 in the 860s, 3 in the 870s.
Still, for a gun that origionally had a es of 12 with the majority of the velocities between 900 and 895 and a real tack driver ... to a gun where I have no real idea where it is going to hit within a 2.5 inch circle at 60 yards is not acceptable to me either for target practice or small game hunting.
