124gn Hammer Hunter in a .300WSM - powder recommendations?

[venatic]

N550 is faster burning than H4350 in spite of what burn rate charts say. I use it quite a bit in 6mm/ 6.5 Creedmoor and you can't load up to H4350 levels without excessive pressures. There are several posts by Laurie over on Accurate Shooter discussing and he puts it closer to Varget than H4350... I added that last sentence because no one should believe what one guy on the Internet says.
