Has anyone pulled apart their favorite factory loads and measured the powder charge and type in order to recreate a favorite load? I'm getting ready to do so on some PPU .375's as my Model 70 really loves the 300gr RNSP load. It shoots it very well so I thought I'd buy components and duplicate it. PPU being European it is my presumption that they are likely using a powder I will not be familiar with. Does anyone have any ideas offhand what they may be using?
