A bit more research overnight and I'm going to try 60% of maximum loads of 2206H (H4895) with pure wool wads first. I use 2208 (varget) for my full power loads but I'm not sure how low I could go.

CaptCurl I'll let you know what happens.

Yes - the ADI version of H4895 is what I'd use - 50% or more is OK, but I'd also use a filler - I've come to prefer a compressed wad of Kapok for this in my .450 Alaskan with 1/2 case of H4895.

Varget would also work, I suspect.
Either powder will take the 9.3x62 to the top with jacketed or cast.
I suspect a heat treated bullet will surprise you as to what it will 'take'. I've shot them in a .375H&H to 2,800fps - 270gr. CAST- no leading, using LBT Blue.

The harder bullet and better lube is needed for higher velocity loads. In the 9.3x62, I suspect SPG might let you down around 2,100fps - just a gut feeling.
