Unlikely to be anything commercially available today. And it's a bit of a fools errand tbh. If it shoots well, it does so in spite of 70 year old ball powder, not because of it. There's no way you won't get equally good (or better) results using some ADI extruded powder. 2206H, 2208, maybe 2209.
I loaded some 125gr AK bullets using some spare H335 that went well too.
