Re: What powder is used by nosler
Not sure what Nosler uses, but of the powders you listed, I would start with H4831SC then go to IMR4350, H4350 and RL19.
I like H1000 in my .300ZWinMag with the 185gn Berger VLD and 190gn SMK. Both of these bullets shoot into one ragged hole with their respective loads.
I haven't bought factory ammo in decades but I would disassemble a cartridge and have a look. JohnnyK.
