I've been loading 45 acp too.. I found some cast 230gr RN, some cast 200gr SWC's, some 230gr FMJ & some 185gr JSWC's..in my bullet stash.
I was impressed with how much 45 brass I've accumulated.. I had a fair amount of 45 acp already loaded. (Guess I've been shooting more 9mm than 45's in my 1911's.) I loaded almost 1K of the mentioned bullets, and just found some Coated 200gr SWC Bayou bullets and another box of cast 200gr.SWC's.
I had decided I wouldn't shoot cast bullets anymore, I like the lead free barrels that coated bullets provide. Realizing how long it now takes to get an order of coated bullets, I'm really happy that I had a fair amount of cast bullets on hand,to load, so I can still shoot as much as I want.
