[QUOTE="Gregg C, post: 1385848, member: 103471"] That is very interesting. I load US869 in my 338-378 why. Listed loads for that cartridge are always (pressure) in Copper Units of Pressure, not PSI. Don't know why, do know there is no co relation. Any way, US869 is seemingly low in pressure for velocity. For instance, max load shown for 300gr SMK shows pressure at 48,700cup, producing 2782fps in their test rifle. Retumbo is shown with 53,000cup, producing 2818fps. Always wondered why the manufacturer doesn't bring the pressures on different powders to equal or near equal values. Anybody got any ideas on that ? Might help me sleep better at night.....
