[QUOTE="J E Custom, post: 1217785, member: 2736"] You are correct. I knew that different cartridges had a different/inconsistent relationship between CUPs and PSIs but I wanted to have something to see what differences there were to be able to use some of my older loads with confidence. Most new loading manuals are very conservative and people tend to start loading at or near max because of it. In comparison, the older manuals have loads that are truly max and should be approached with caution. with the changes in cartridge designs that people are making starting loads should be lower if anything but SAMME specifications are used and even then it is still recommended to start low. I have found a good guideline that works, and SAMME has set a Standard comparison that will help. I now have a good grasp of the differences and feel more comfortable with them. Some of the revised SAMME pressures are now lower and I agree that They should be from past loading experiences. Anyway, Thanks to all for posting. J E CUSTOM [/QUOTE]
