This is what QL shows for it. I have been seeing RL26 using a little less charge weight to attain the predicted speed in a few cartridges, but it looks fairly possible.
I saw the same thing. Fotis ran QL for me with the 7 SAUM and a 150 grain bullet and I was getting over 150 fps more than what QL predicted for the given charge weight.
So I'd be careful with the loads that are "approaching maximum" and I'd be willing to bet that you get to the listed velocities (and pressures) with a few grains less R-26 than QL would indicate. At least in the 7 SAUM.
