I think the reduce load problem is with slow ball powders primarily.
I use a lot of 45 colt loads in my 454 casull brass. One of my favorites is 11g of Universal over a Hornady 250g XTP HP. Enough pressure to make it work good, but not so much as to be overbearing recoil. 2400 is another good powder to use for less than maximum casull loads.
Using these methods, I don't have to worry about the crud ring which is a much discussed topic.
Have at it!
