I didn't pass judgement, I just said I wouldn't do it.
Yeah, there are great 220-230gr loads but as I said, the heaviest 10mm loads are only equivalent to the Keith .44Spl load. Sorry but I wouldn't shoot a Cape buffalo with a standard weight bullet out of any handgun. I want the biggest friggin' hammer I can hit with.
How is it like the Keith load? Different caliber, different weight-for-caliber, hugely different nose profile. If they both go 1,200 fps then that is the only similarity I can draw between them. I don't understand the correlation.
The velocity is actually in a good range for cast bullets.
