Hey Sparky...
You're probably going to get a lot of opinions on this question and I'd be inclined to believe most of them. There are lots and lots of good 45 cal. bullet molds out there nowadays. For what it's worth, here's my opinion. I've long used the RCBS 500 BPC bullet mold and have no complaints whatsoever. It usually weighs between 508 and 515 grains from my mold depending on how accurate my alloy is. I shoot 25-1, or try to, and segregate my bullets into batches of + or - 1 grain. It works fine for me.
If you like a bore rider, and I do, the old Lyman 457125 is a fine bullet, provided it fits your bore. From my mold with the same alloy they go around 520 grs. It has been the most consistently accurate bullet in a variety of 45 caliber rifles for me for a long time. I don't believe it holds up as well as other bullet designs beyond 300 yards but it is a grand old bullet. It's also a bit more economical than the RCBS but I don't believe the Lyman molds are as robust, especially the sprue plate.
You can spend a lot more money for molds from custom makers and I have some, they're very good, but I believe a good starting place would be the RCBS mold. I expect they've become pretty expensive too since I bought mine.
Brass.....mostly I have Winchester cases because that's what I had when I started shooting BPCR's. Starline, Remington, Federal...I've used them all with equal success......as long as I segregate the cases by weight and index the bullets when I seat them.
Dies....any of the major players, RCBS, Lyman, Pacific, Hornady......I'm not particularly fond of Lee but they're certainly adequate. That's my opinion and it's worth what you paid for it.....hehehe.
