Right, I have a new Uberti Cattleman and a new model Ruger Vaquero. I started at 8.0 and worked to 8.5. I couldn’t tell the difference shooting them but preferred the case fill. They drop out of the cylinders with a little tap. Primers are very rounded with zero signs of flattening.
I mention that because my standard .45 Colt pistol load is 9.5grn Unique under a 250-255grn cast... which is fine in a big frame Ruger (like my Vaquero was...) but that load pushes 20K PSI, which may be too much for some pistols. It's important to know what you have, and what the manufacturer says it can take.
