Loading the .458 with 350gr bullets

[MAKATEUS]

Hi guys.

i am looking for some help on load data when it comes to the 350gr bullets for my .458.
i usualy load 74gr S321 behind a 300gr Impala bullet but don't know what to do on a premium 350gr as the impala is solid brass?

any help would be apreciated.

Are you in RSA and only have access to Somchem powders?

Which 350gr bullet are you planning to load?

People with their Quickload program can probably help.
