If you decide to cast, I wanna say that these 200 gr RNFP Lee bullets have been something of a wonder for me, in just about every load I've thrown at them. Now, these would be mostly coming out of an M&P 45c compact, but they did very well from a P220 full size as well. I can hardly make 'em fast enough...they're fairly economical at 208 gr in wheel weight lead, have fed very well for me, and they punch paper like wadcutters.
Bless you for inspiring me to reconfigure the press and get to pounding these out in mass quantities. I've been loading them in 45 Win Mag and pushing them to what has to be ungodly velocities, and they do just as well there, too.
Yet ONE MORE thing about loading 45 Auto...because even heavy loads are still reasonable for the case, if you load moderate loads you can expect your brass to live pretty much forever. Definitely long enough that for any cost-calculations you can totally ignore it--it simply doesn't factor in to per-round costs. It starts out low or zero, and goes down from there.
One thing not told to most beginners is don't crimp and seat in one step. Seat the bullet and then crimp...
I've done it both ways because of the dies I happened to have. But, I have to agree with Tony on this simply because it's simple--you decouple the operations and it's a no brainer to do 1) bullet seat depth, got it, then 2) take the mouth bell out...got it.
As has been stated so many times--you gotta expand the mouth of the case so that when you place a bullet, it 'sticks'. On a progressive this is especially important since the cartridge 'assembly' gets a lot of jerking around, at least on a Hornady press. You put in just enough 'bell' to seldom if ever see a bullet get cocked by shellplate rotation (press cycling), and to never see a cast bullet get 'shaved'.
Then you adjust that crimper, IMO, so they look like the cases in my photos above--this is MY OPINION--you see no inward crimp at all, you see a straight wall case with no bell and no space between the mouth and the bullet itself. But no inward crimp whatsoever. Completely uneeded for a big fat case loaded with 4 gr of propellant, and the last thing you want is for the case to not stop cold on the end of the chamber shoulder.
Have fun! I have to think one of the 3 or 4 greatest auto pistol cartridges ever designed, maybe in the top 2.
