Don't know if this helps but Vihtavuori N130 is listed as an "equivalent" for AR2207/H4198 and Vihtavuori have load data for 9.3x62 and 285/286 gr projectiles using N130 here https://www.vihtavuori.com/reloading.../?cartridge=92

Greetings,
That is some interesting data. Based on that the 48 grain load of AR2207 looks a bit stout but perhaps not so much with the PPU projectile which is likely to be softer. A better longer term option might be to switch to AR2206H for which pressure tested data is available and is easily downloaded to the velocity you require. I don't know what the availability of AR2206H powder is not having bought powder for several years but it is the can that I get of the safe most often when I am loading.
Regards Grandpamac.
