I got out of the 1911 game before I started casting. The majority of my 1911 experience was with jacketed bullets or commercial cast bullets with a small amount of factory cartridges in the mix. In those days WW-231 was my primary powder and WSF was the secondary.
The 200 gr SWC (H&G #68 or one of the clones) still seems to be "The" bullet for most folks that shoot cast bullets in the 1911.
So, with a SAECO #069 or a RCBS 45-201-SWC, what would be the powder of choice for a 45 ACP load?
