    The merits of reloading, and casting for, .45 ACP

    I got started with revolvers, back in late 2008. This was because my Dad had revolvers his whole adult life, and I always thought they were neat. Still do. Semi-autos seemed a bit too complicated for me, first starting out.

    Didn't take long to learn to appreciate the semi-autos as well, though. My first was a 9mm, a Ruger SR9. These were pretty nice, and very affordable, copies of the Glock 17 and 19 pistols. Then Ruger came out with the SR45, which is basically their version of the Glock 21, also very affordable. It's a fine shooting pistol.

    And then I learned about 1911's. Yes, John Moses Browning was a singlar genius.

    That also meant that, like my beloved .45 Colt, you easily can end up in the poorhouse if you shoot a lot of .45 ACP and don't reload it. So, I picked up a set of dies (Lee, in my case) and got to it. Figured it'd be more complex than reloading rimmed revolver cases.

    Fortunately, I was wrong. Turns out reloading .45 ACP is easy, just as easy as the rimmed cartridges. The only difference is taper-crimping vs. roll-crimping. Just flatten out the flare; nothing more is needed.

    The .45 ACP cartridge doesn't need a lot of powder. About 5gr of Bullseye or Titegroup, with a 200gr home-cast bullet, makes a good shootin' load. Same goes for 4.5gr of either powder with a 230-gr cast bullet. Yes, I cast my own bullets, which makes the cartridge very economical to reload. My bullet lube of choice is liquid Alox/Xlox, because it works well and I can lube 1,000 bullets in 5 minutes. Brass is quite available. Also, my per-cartridge cost took quite a helpful nose-dive from that of factory fare.

    The cartridge has some kick, being a .45-caliber. Due to the semi-auto action of most firearms chambered for it, the minimum power is higher than it would be for an equivalent revolver cartridge, to cycle the action. But even then, it's not at all unmanageable, especially in an all-metal 1911. Even my wife can handle it, although it's not her favorite (she prefers .38 Special). I quite like it.

    Finally, it's a quintesentially 'Murrican cartridge. :-) My understanding is that some Special Forces units continue to use the .45 ACP for their sidearms. Not saying the 9mm or .40 S&W are bad cartridges; not at all. I'm simply pointing out that the .45 ACP is just plain fun to shoot and a very good candidate for reloading.

    I use the same 200gr cast bullet (LRNFP style) for both .45 Colt and .45 ACP. It feeds just fine in every .45 ACP pistol that I've tried.

    If you do shoot .45 ACP, or are thinking about it but don't because 9mm factory ammo is cheaper (and it is!), consider reloading for the cartridge. I think you might find it fruitful, satisfying, and even fun. There's just something really cool about shooting ammo that you made yourself.

    I have both, and others too! That allows me to have more and shoot more.

      In light of a very recent thread about different primer sizes with .45 ACP, I think I'd be remiss not to mention something about that.

      SAAMI spec, of course, lists a large pistol primer (LPP) for this cartridge. However, small pistol primer (SPP) versions came out some years ago because they use the "lead-free" primers. For reasons too long to go into (it involves something called "brisance" of the primer compound), apparently the lead-free versions come only in SPP form.

      This can become a major annoyance when reloading .45 ACP if you don't check the primer size of each case and sort them accordingly. Some people consider the SPP version of the case as the spawn of the Devil and immediately toss them out. I don't do that. I simply separate them out, and it really doesn't take much time. You should be inspecting your cases for splits and other defects anyway. :-)

      So, I'll wait until I get about 200 or so SPP cases (by now I have considerably more than that). Then, I'll do a batch, using the same load as for the LPP cases. These rounds fire just as well, just as precisely, and just as reliably out of every firearm in which I've tried them. So, they do work very well. Just keep them separate. Then, police your brass like you normally do, and take a moment to separate the SPP's from the LPP's. Reload, enjoy, police...rinse and repeat. This makes a nice, wide grin appear on my face. :-)

        Hiya Cowboy and thanks as always for your informative posts.

        How much time does casting take / how many per hour can you produce? I’m new to reloading (under a year) so not looking to start something else new yet, but I’m curious.

        I know primers have risen in price in recent years - what about projectiles? Have their prices changed meaningfully as well or not? (And afaik powder is apparently more expensive but given how many rounds per pound for pistol, it’s a small factor as I understand it).

          New to reloading, eh? Welcome to the fraternity! We all had to learn, and we all had exactly ZERO experience before we did our first rounds.

          Projectiles have risen in price some, yes, but I wouldn't have called them "cheap" even in 2009, when I started reloading. The price and availability of projectiles is why I learned how to cast, starting back then. I continue to cast for the same reasons today. Not only do you save a lot of money per round, you also ensure that you actually have projectiles to reload. Given the "mommy, may I?" laws about ammo in California these days, I consider reloading, including casting, especially important.

          In an hour? I've been known to do 1,000 with a Lee 6-cavity mould, for several hours straight at a time. Actually, there was one winter weekend when I spent about 11 hours, about 6 on Saturday and 5 on Sunday. When I was done, I had over 11,000 bullets ready to be lubed. Now, this was the 358-105-SWC (105gr) mould that I use for the .38 Special "powder-puff" load. For the 200gr LRNFP's that I use for .45 Colt and .45 ACP, it's about 800/hour.

          Lubing those bullets, I have a video in which I show you how to do 1,000 in 5 minutes. In practice, I've upped that to 2,000 bullets in 5 minutes of work. Let the liquid Alox/Xlox dry overnight, and you're ready to build ammo with those bullets the next day.

              Never cast any projectiles myself, but I've read it's best to cast during spring/fall outside. Reason being the fumes generated by the lead no bueno to inhale especially in a small room. Just my 2¢.

                i cast many thousands on a coleman stove and a 6"cast iron skillet

                i used to buy bear creek bullets still have many rounds loaded up with them i feel bad i'll probably die with unshot reloads

                for years used the lee 2 cavity molds and lee liquid alox and the push though sizing die

                dang youtube deleted my video of casting

                shake and bake powdercoating is the best option now (at least when harbor freight had the powder cheap)

                  Anyone load 45 ACP up to 460 Rowland pressure for a factory Glock 21 barrel?

                    That probably wouldn't be a good idea.

                      Just to reinforce that point, this is an after market barrel.



                      Also, even if the brass held up, which it probably won't with that chamber, the slide will beat up the frame.

                      This was from a Glock 21 with a long slide and a 6" barrel



                      It was a lbt 220 FNB at 1.24 oal in SPP brass.

                        YouTube folks are deleting my casting and reloading videos as well. That's why I host my videos on my own Web site, which I also have physical possession of. It's good to be an IT engineer. :-)

                        Your setup has worked for well for over 100 years with bullet casters. Another good one, that I happen to use, is the Lee Pro 4-20 melting pot.

                        And to Grendel Guy's point, yes, I do cast outside, in either winter or early spring. This is so I don't overheat from all the leather protective gear that I wear while casting.
