here is some help
I load a lot of 45 Colt (Long Colt) in a Ruger with 9.0 grains of Universal, any 230 grain FMJ that is cheap, and seat it to 1.650". These are good practice loads. My one Vaquero has digested close to 18,000 of this load. It shoots close to point of impact of a 250 grain loaded with 10.0 grains of Unique. The load also prints close to my carry load of 9.8 grains of N340 under 230 grain Speer Gold Dots.
As far as FMJ go I use a bunch of Rainiers and Berry's. Yeah, I know they are plated and not a true FMJ, but they are similar in profile. I also have used Remingtons and Winchesters when the price is right.
Hope this helps.
(edit: I don't use a cannelure at all just a taper crimp die.)
