The 308 norma magnum has the same case capacity as the 30/338 so if you at the load
data for the 308 NM you should be able to find plenty of good loads,
These cartridges are not interchangeable but the load data is the same and if you start low
you will have no problems.
When I was shooting a 30/338 there was no 869 powder so I have no experience with this
combination. I used the old standby 4831.
