I don't mean to quibble, just curious. Didn't Tony Boyer shoot a Wichita? If so, there may have been a Super Shoot win for Wichita at some point.
The standard Wichita has a heavy bolt lift, but it can be considerably reduced by modifying the spring and ramp. It has larger lugs than a BAT, which provides more bearing area. The sliding extractor also doesn't weaken the bolt head as much as the Sako type. (Can you tell I like them, too?
) If one were so inclined, adding a roller on the cocking piece I think could make an old Wichita as smooth as any other 3-lug. It would be a unique and, I think, competitive action.
Cheers,
Keith
