RL22 loads for 6.5 WSM wildcat? Superformance?

[Cheezie]

Looking for any load info with either of those powders for my néw build, a 6.5 WSM 26" sporter contour with 8:1 twist. Action is a Savage DBM.
I have both those powders and 140 gr SST's on hand for load development and will also be trying some Hammers of a similar weight.
Published loads seem hard to find and phone calls to powder mfrs didn't produce much guidance either. Closest I've come so far for a starting point is 270 WSM data.
Thanks very much.

No personal experience with 6.5 WSM, but I've attached some QL data for the 140 SST, 137 Hammer Hunter and 139 Shock Hammer. The data is listed in QL as 6.5 Rock (WSM). Recommend you compare your actual case capacity to QL data and as always, start low.
