No pressure signs but it's right on the edge according to QL (just under 63K). I think it's part barrel and part RL 26. Barrel and build is a HCA and Mike mentioned his barrel tend to produce a little extra speed but the RL26 which QL shows about 40fps faster than N-560 was actually almost 80fps faster than N560. I did try RL16 which would be the closet powder I have to the Staball 6.5 was not even close to RL 26.
I'd have to look but RL16 was around 100fps slower showing a light ejector hit. My COL is 3.088 so not a true short action.
