What I've cast so far in 9mm is the 124-grain TC in Lee 6-cavity molds. Haven't worked up any loads or tried any of them so far, and may well go to 147's to allow use of softer alloys & avoid additive costs.
Main deal with these is that they're solely intended for close-in, fast use on steel using a timer. So I don't care as much as I typically would about accuracy, consistency, or tweeking to get the best performance; I just want these for use with time drills to build speed.
Right now, I'm running in the mid to high two-seconds (2.45 is my best, 2.77 or so is typical) for six shots on three 12" plates at 30 feet; two shots per plate. I can sometimes best two seconds with a .22 kit on a 1911, but never with centerfire. And to be fair, that's not cold times either; it's after warmup runs.
Also, I think 7 yards is more realistic for defensive purposes than the 10 I'm shooting at now, and will be more comfortable shooting steel at 7 yards with lead bullets than with jacketed.
For purposes other than this (hunting, carry, target shooting), I'll stick with my old standby loads; some commercial, some loaded. Just looking to knock out rounds that go 'bang' and fly reasonably straight at short range.
I actually don't mind the time used up in this. It's pretty much a recreational thing for me, whether I'm using bought bullets or casting my own, and there's a strong cheapskate gene somewhere inside me that loves the fact that I've got ~20,000 rounds of bullet material for little cost and a modicum of effort. I spent probably 6-8 hours total and less than a tank of propane sorting out non-lead wheelweights and melting/fluxing into ingots. After that, two evenings of maybe two hours each got me around 850 9mm bullets and 800 .38spl bullets; using only 28 lbs or so of my 417 lbs of material. One nice thing about being rural as we are, I can actually still get free wheelweights from a few places. Got about a 1/3-full five-gallon bucket yesterday in fact when I had my oil changed; probably 40 lbs as it sits and maybe 25-30 lbs of usable lead to be had out of it someday, whenever I want to mess with it.
