wow...I've found serious discrepancies in loading data between manuals and it gives credence to starting 10% low and working up.....The best manuals that I've seen are Hodgdon's data manual and Hornady's Handbook of cartridge reloading....

.30-06.....use H-4831
.30-30.....use H-4895
6.5X55.....use reloader 22
.357 mag...use H4227

Loads for the 150 grain .30-06 can be used for all 150 grain bullets...etc.....it's a dern good rule of thumb.....!
