Well I don't have a chrony so I can't give any #s, but it is the hardest hitting springer I have. It has been deburred and lubed, no buzz or twang when firing,cocks smooth and has nice lockup. It does not have a hole for a stop pin, or a scope stop so a solid 1 piece mount will be needed for a scope. It is made by Daisy, for Winchester, so it is basicly the same as the Powerline, except with a walnut stock. It was a beast like the powerline, but after a lube job and some trigger work, is quite nice. Only reason I'm seeling is the boss said no more until a few are gone, so my S1K may be next. If anyone has any ?'s send me a PM.
