45acp, 45lc and 45-70 bullets from acp cases??

[rockrat]

Wondering if anyone has tried this. I would think you could take some of the Lee push thru dies and size down 45 acp cases to .451" or so and use the cases to make bullets for 45 colt and 45-70(use the .457 push thru die) with the proper swaging setup. Probably use a 44cal boolit for a core. Anyone tried this?

Rockrat:

I've been playing with that idea for a while now and come to a few conclusions of my own.

I tried running the un-annealed .45 ACP cases thru a 0.456 swaging die, and they passed thru like butter. I opted to deprime and clean the cases before hand, and I don't like the idea of leaving the spent primer intact. Problem is I don't think that the rim of the case is going to help with the aerodynamics of the bullet either, I could be totally wrong here, but that's my opinion.

So I machined off some of the material at the back of the case, just enough to remove the primer pocket, and no more. Now with the primer pocket gone, the case looks more like a jacket.

Here's a few pics of those now machined cases:





The real reason behind all of this was to see what kind of "uniformity" I could get after machining the cases. I grabbed 11 cases, 7 were WCC, and the other 4 were TZZ. After machining the primer pocket off, I weighed each case and was pretty suprised at the result.

Here's what the WCC cases weighed after machining:

49.9
50.1
49.2
49.7
49.7
49.6
49.8

Out of the 7 cases, the average weight was 49.71 grains. Not a bad average and not much deviation amongst the cases.

The one thing with bullet swaging is consistancy. Everything has to weigh the same, all the core must weigh the same, all the jackets must weigh the same, the same amount of force should be applied for each operation and so forth.

Back to your question, "will they work", sure they will. With proper tooling you can do anything. The use of brass cases for jackets will undoubtedly be a real money saver for those who swage. And the possibilities are limited only to your imagination.

Just my thoughts, FWIW.

I'm just wondering, are you guys married? To a woman I mean. It seems that you have an awful lot of free time to do all that there think'in.

[rockrat]

I am married to the most wonderful woman. As long as she is warm, loved, decent food and clothes and the car works, she could care less what guns I buy and lets me "play" in the shop when I feel the need. Course, I work at home, and when she goes to work (part time), thats when I usually go out to the shop.

Rick,

Awesome! Curious what was the weight varaition before you turned down the heads. Wish I had a lathe. Aerodinamics, I have thought about too with the rim still on. Nicely done, Cool pics.

Good shooting,

Brian

I've been married for over 30 years to wonderful women as well. I guess after that amount of time, whatever I do, doesn't really matter. My wife works full-time, so when she's not around, I play in the shop. Actually, even when she is home, I still play in the shop. Life is good.

Brian:

The weight of the cases, before removing the rim and primer pocket was very consistant as well. Since the cases were once fired only, and had not been trimmed or loaded previously, they held a constant weight. I don't know if this would apply to all manufacturers cases, but the WCC cases were pretty good.

Wonder how it would work if you just turned the rim off. Kind of a boattail bullet.

That would probably work well. You would need a base punch that closely matches the "Taper" left on the base of the case after machining. Otherwise, when seating the core or forming the ogive, the base will be swaged flat. You'll need to support the existing base.

Another possibility to explore further.

I bought my wife a Jaguar XK-8 convertible. She let me go to Africa buffalo hunting, and pretty much do what I want.

Rick,

How did you get your cases and primer pocket so clean?

[BT Sniper]

Any pics of a .457 finished bullet from a pistol case? What kind of weight would you shoot threw a 45-70?

[docone31]

How is the brass against the bore? It is harder than copper.
A lot of work, but, you never know down the road.

Rick,

Ceramic media, it's the only way to go.

After some hesitation, and some convincing by Montana Charlie, I took the plunge and bought some, and never looked back. As a matter of fact, I threw away all of my corn-cob and walnut polishing media.

Tumbling time will depend on how dirty the brass is. The cases pictured in the previous post were "range" brass that was extremely tarnished, the cases were actually black.

I put about 300 cases into my tumbler barrel, added enough ceramic media to cover the brass, water (enough to cover) and some mild dish soap. Let tumble for eight hours, strain, rinse and your done.

No vibrating polisher using corn-cob or walnut will clean as well as the ceramic media.

I found that my BP cases came out as clean and bright as the day they were made, inside as well as the outside.

Ceramic is the only way to go.

What is brass made from?

The same two materials we've been pushing down our barrels for years. So, I don't see it being a problem.

Have had no problem cleaning bore and have fired a couple hundred 44's down the tube.

Thanks Rick, There is alot of different ceramic media out there. I got some and use the same technique but mine was a lee brand and said it was for appling moly coat to bullets. If I leave it in to long it starts to coat the bullets with the dirty film.

So exactly what kind of media did you use? Oh yeh, I used mine in a vibrating poliser rather than tumbler. Tumblers are $$$ any recamendations?

I used Non-Abrasive 5/32" x 5/16" media, available from Kingsley North, Inc., (www.kingsleynorth.com). Price is reasonable, $16.00 for 5 lbs.

And for the tumbler, I have a Thumbler Tumbler model AR-6. They do have larger capacity tumblers, which would be better, but the AR-6 works good enough for my needs.

Did alittle experimenting today. Turned off the rim to match the shape of the end of the case. Don't actually have .457 dies yet but was able to reduce the case and rim in my 44 dies. Was easy like Rick said. With no core yet I just seated a 270 grain .429 bullet in the jacket. Smoothed it up alittle in the drill press and now have a 350 grain bullet. Not shootable yet but a fun idea.

Rick how long would you guess it would take to turn down 100 cases like you did?

[Red River Rick]

BT Sniper:

It shouldn't take more than 1/2 - 3/4 of an hour, or less than that to do 100 cases. If you set up your lathe with a stop inside the spindle, it'll go fast.

I was also thinking of making a set of soft jaws for my Kurt vice, machining a bunch of pockets to hold about 10 rounds at a time and then do them on my CNC mill. Then you could probably spit them out really fast. It would take longer to load and unload than it would to machine the bases off.

I boat tailed a bunch of 30/06 cases and 45acp cases for this use about a year ago in my lathe. Pushed them all through a .458 sizer. Some before annealing and some after annealing. I'm waiting on a swage die set for .458 to wonder my way.

FYI, The guy who invented the 450 and 50 Alaskan made brush buster slugs using 45acp cases for jackets if I recall correctly. For the 50 Alaskan he used a 50 BMG bullet cut in half and inverted. boat tail first which was pure hell on game.

Going off a tired memory from a hard day of studying and working Bullet jacket material is 90% copper 10% zinc and "cartridge brass" as its known in the industry is 70% copper 30%zinc...something like that I THINK. Its in one of my books back at my apartment but I'm not there right now.
