Hi. It's hard to compare 'em as Hodgdon gives 4064 pressures in CUP and 4166 in PSI for the .243 data. There is no converting that one to the other either. I'm just thinking velocities with a given load. Mind you, their .260 data shows slightly less powder gives slightly less speed, but more pressure with the 4166. Don't think it makes much difference.
