Any good load data that anyone has on an AI .338 Norma Mag?
Your case capacity should be really close to a .338 RUM and slightly less than a .338 Edge. I would start with 338 RUM data starting low and working up.
Thanks I will try that. I am fire forming some Norma Mags now for it, well once I get to the range.
What is the case capacity difference in the RUM and AI Norma Mag?
In my 30-338 Norma Imp I'm about 3-4 grains below a 300RUM (the same case as a Edge.) I didn't compare it to a 338 RUM but they are down about the same from a 338 Edge so you should be able to use 338 RUM data. The good thing is the Norma brass is better than the Remington RUM brass.
