A couple of things on the Quickload print out. It uses 55,000 psi or the SAMMI maximum pressure and it is off on R26 as it is listed as slower than R25 which it is not at least in mid sized cases. You would need to recalculate it with your own velocities to get it more accurate.
I had pressure spikes above 90 degrees at around 53 gr. with 130 grain bullets, I backed down to 51.5 grains so I could shoot them in hot weather, this was with magnum primers so that could have run pressure up some too.
