.357 Remington Maximum Published Data?

[WhiskeyTango13F]

I have somewhere around 40 reloading manuals going back 45 years up to and including 1981 when .357 Max was fielded. I have not been able to find any published data online or in manuals for 158gr Hard Cast SWC and 4227, 110 or 296. Is there any out there from a manufacturer? I am loading for a Ruger Blackhawk 7.5" which is built on the Super Blackhawk Frame/Cylinder that is hell bent for stout.

I load jacketed data in 380,38 short 9×17 ,38 Spcl, &357 with no ill effects.

The cast will occupy slightly less case space than jacketed .
Lead is more slippery than copper.
Because cast is typically shorter via the nose dimensions this too reduces case intrusion at a given length .
