Pure lead bullet with a gas check?

[Goofy]

I use pure lead paper patch 300 gr in the .44 mag. MV is 1600 FPS +\- Tracking not required.

If I'm not mistaken, the original Remington .357 factory loads were made like that and coated with a heavy wax lubricant. They shot well but they leaded some too./beagle

I shot some of those type back in the 1970's through my .357 Ruger Blackhawk. They were Winchester 158 gr "Luballoy" SWC's. After shooting some of them, I couldn't hit a Tide Box @ 25 yards. Never had before or since a barrel that was leaded up so bad.
