Any downsides to aluminum casings over brass if you aren't

nah

Range vultures will call you names.

I personally pick them up anyway and into the recycling bin it goes

>>31316919
Is there such a thing as Aluminum rifle casings? I've only ever seen pistol cartridges.

brass shells on the other hand...

Aluminum and steel cased is not safe for blowback operated firearms.

My range won't let you use them

>>31317277
9mm makarov is used in makarovs and is generally steel cased

>>31317489
Yeah, but 9×18 isn't particularly high pressured

>>31316919
My CZ-75 has issues cycling them, and I always get unburnt powder on my arms afterwards. Somethings fucky with them and I can't figure it out.

>>31317489

Just say 9x18

>My CZ-75 has issues cycling them, and I always get unburnt powder on my arms afterwards. Somethings fucky with them and I can't figure it out.

Aluminum is too soft of metal for cz master race

>>31317285
Your range is retarded.

I bought some Remington aluminum 9 mm and one of the bullets fell apart when I extracted it. I might have a picture. Gimme a few.

>>31317080
those are some sexy shells.

>>31317285
do they say it damages the berm?

>>31317559
>Yeah, but 9×18 isn't particularly high pressured

>9×18mm max pressure = 160 MPa
>.380 ACP (9×17mm) max pressure = 148 MPa
>.32 ACP (7.65×17mmSR) max pressure = 141 MPa
>.25 ACP (6.35×16mmSR) max pressure = 25000 CUP, for which there isn't an accurate conversion to MPa, but it's proofed at 156 MPa
>.22lr (5.6×15mmR) max pressure = 145 MPa

I don't think pressure is anything to worry about in blowbacks. and if you're wondering about Hi-Points...

>9×19mm max pressure = 235 MPa
>.40 S&W (10×22mm) max pressure = 240 MPa
>.45 ACP (11.43×23mm) max pressure = 140 MPa

So maybe it'd be a problem in 9mm and .40 Hi-Points, but I still doubt you'd have a KB just from using steel or aluminum cases.

>>31318393
Keltec s2k is the gun I had in mind, and aluminum case has given me problems.

>>31318619
Were you experiencing ruptured cases, or did the gun just not like it?

>>31316919
not really, I put 150 rounds of federal aluminum cased ammo through my beretta and had zero issues

>>31317700
>>31318065
They said they use a magnet to pick up brass, then sweep up all the steel, but since the magnet picks up aluminum too, they have to hand sort all the brass looking for it, which seems reasonable.

>>31318844
Err, other way around. The magnet picks up steel, then they have to hand pick aluminum

>>31317277
Says who? I have run them all day in my 92A1 with no difference from brass other than loaded magazine weight.

Neither aluminum nor brass are attracted by a magnet. Steel is.

Try again.

>>31321310
Im sure what the range told this idiot is, steel and brass can be sorted with a magnet, aluminum and brass cannot.

>>31316962
It's been experimented with, but high pressure rifle cartridges often exhibit a "burn through" effect on the case heads. Thus it typically isn't used.

To answer OP's question, there's typically no issues caused by using aluminum for pistol cartridge cases.

However, bc most aluminum cased ammo is intended to cheap low end stuff, you might have accuracy or reliability issues related to poor QC or substandard components.

I might not grasp the concept of its semi-auto operation, but I know for a fact it does not tilt to feed.

Not true... You can use steel cased .308 in HK roller locked firearms.

Not so much in the tilting bolt gas operated FAL, which tends to rip off case heads.

>>31322681
Just keep posting then.

>>31322681
If you might not grasp semi auto operation wtf are you arguing about it, and losing? Fucking Google my dull friend.

>>31318393
What were you trying to prove by posting pressures of weaker cartridges than 9x18 and then posting 9mm Luger with much higher pressures reassuring that 9x18 isn't a high pressure cartridge?
Kind of dumb if you think about it.

>>31322648

berettas use a walther locking block recoil system you fucking nogunz faggots

not all pistols use browning tilt barrel recoil systems to accomplish delayed blowback.

Some guns won't like aluminum cases, giving you less reliable ejection and extraction.
Some guns won't complain though, so it can be for cheap shooting.

Why wouldn't you?

>>31322464
The hilarious thing is that the end result is the same - aluminum and brass cases cannot be sorted with a magnet. He's right by virtue of two wrongs cancelling each other out.

>>31325163
Nigger, it's too flimsy, you're not supposed to reload it, you're supposed to recycle it.

>>31324602
Yes, that's because it is the hottest round you could use in a straight blowback design.
But compared to 9mm Luger which I consider the average it is no were near that kind of pressure.

>>31326857
9×19 isn't the average for blowbacks though. 9mm is above average. If you want to go in to sub-caliber carbines and SMG's, we can do that too. The MP5, which is regarded by many as the best subgun ever made, is roller delayed even in 9×19mm. Meanwhile the PPD-40 and PPSh-41 are open bolt, straight blowbacks, and they don't KB when you put steel cased 7.62×25mm through them, despite the fact that 7.62×25mm has a max pressure of 250 MPa while 9×19mm has a max pressure of 235 MPa.

>>31327326
I was referring to pistol cartridges in general, not just blowback designed handguns.

>>31325099
Proofs?

>>31327459
Tula doesn't FTF or FTE even close to as often, nor is it as dirty.

>>31327545
Shot just fine out of my sig.
What kind of pistol was is ?

>>31327443
Well the conversation goes back to >>31317277 and was about straight blowbacks.

>>31325089
>less reliable ejection and extraction.

This may be a factor. Look up aluminum and steel galling. The barrel alloy might be a factor in performance differences.

>>31316962
only thing I'm aware of is some wood bullet blanks for .30-06
I have one in my collection, Belgian IIRC

>>31328070
With blanks, it's different, because the pressure isn't contained even close to as long, I'm thinking you could make blanks out of aluminum and they'd do their job.

i bought steel case 9mm ammo once by mistake at walmart. Went to the range, i rented a gun just so i could finish that box, refused to use it in my own. You could see the trail of burning powder in the air as if they were tracers. Dirtier than hilary. Very happy with my decision.

>>31328137
Just clean your gun later you dainty fuck.

>>31324401
Like cheap bad

>>31322681
Factually incorrect.

This often repeated bullshit is a result, I think, of the open slide making the tilt less noticeable vidually. But it haopens.
Go get your beretta and check it

Like I said, I doubt you'd have a KB.

>>31320160
black powder cartridge always looked fun.

>>31324401
NON OPERATOR.

>>31324602
High Point .45 are straight blow back. That's why the slide is so heavy.

>>31329889
It is. Blackpowder in general can be very fun, you should try a cap & ball revolver some time, loading it takes time but it's almost as fun as shooting it.

>>31330020
Yeah, no shit ace. Hi-Point everything is straight blowback. .45 ACP still has a max pressure of 140 MPa, which is 20 MPa less than 9×18 (160 MPa).

>>31330063
looks like a blast, and chap to shoot- but the nice BP guns are almost as much as a smokeless. I'd really like to do a kit pistol, just so I can say I built something and shot it. Had an old school New Orleans Ace I built from a kit- never shot it though. Cool little gun.

>>31330099
what's MPa? I grew up with Copper Units of Pressure (CUP) and PSI.

And yes, pressure will go up with a smaller bore diameter- look at 12guage vs .410.

>>31316919

Brass is pretty, so I shoot brass.

>>31330419
MPa means MegaPascals, it's a metric pressure unit. A difference of 20 MPa converts to approximately 2901 PSI.

>>31328376

My ex and I used to say stuff like that.

I can't wait until her life derails again, maybe this time she'll kill herself so I can laugh.

>>31330526

>>31320931
>some ammo might be a bit too low in pressure
While this is true, it isn't because of
>because they dont' want to be charged for unsafe ammo
It's because it's cheap ammo and they're cutting every corner they can. While a single grain of powder is a fraction of a cent to individual reloaders (and probably less than that when you're buying hundreds of thousands of pounds as a commercial operation), when you're producing several tens of millions of rounds a year that's big money.

>>31330419
1 MPa ~= 145 PSI
SI units dumb fuck. Also google.

And pressure depends more on the overall round than just bore diameter. .45 ACP is just low pressure.

>>31328266
i clean my gun every damn time i shoot it nigga. there is pussy out there i wouldn't put muh dick in, i feel the same about ammo and my guns.

>>31330631
Guns don't get diseases.

Ive shot aluminum cased out of an mp5, usp, sig and hipower without issue. No issues in any of those firearms.

Same goes for steelcase

>>31330667
And I've had a 92G, a 92FS, a CZ75, a CZ P01, a P226, and 4 different 1911's choke on aluminum (but not steel).

Not all guns are created equal, and anything not made in the USSR prior to ~1989 was intended to be used with brass cases.

Stupid question, but:
HOW does a different case material fuck with extraction, ejection, etc, assuming the dimensions of the cases are within specifications?

>>31330851
Different materials have different properties. Steel, aluminum, and brass obturate differently. When you fire a gun that uses self contained metallic cartridges something called obturation happens, where the pressure and heat inside of the case cause it to swell in the chamber, sealing the breech and "fire forming" the case to the chamber walls. Steel obturates less than brass, and you can actually have some pressure loss because of that, but because it doesn't expand as much it means that in guns like the CETME-L you actually improve extraction by having less friction between the case and the chamber wall.

In addition to obturation, cases act as a heat sink and help in cooling the gun by absorbing a lot of the heat energy of firing and then being ejected. Brass makes a better heat sink than steel since it's more conductive.

How aluminum stacks up against brass and steel for these purposes I'm not sure, but I'd guess it's somewhere in the middle.

>>31330851
They expand at different rates/to different amounts, making extraction from the chamber easier/harder.

Soft rims can be ripped through by extractors, especially if the case expanded into a rough/dirty chamber and isn't super easy to extract.

Not enough case expansion can lead to an incomplete chamber seal, and fouling blow-by, further leading to sticky chambers or gummed up extractors.

>>31330941
Harder materials like steel will also negatively affect the wear on certain parts like the extractor, needing it to be replaced sooner than with brass. It is fairly minor though.

A similar thing also happens with bi-metal jackets and rifling.

>>31330989
>it is fairly minor though
Regarding extractor wear, it's a nonissue. Odds are excellent you will outright break your extractor through normal use long before you wear it out, regardless of what the case material of your ammo is.

>>31330585

After two years? Here's doubting.

/k/- guns and misogyny

>>31330989
I've seen a few pieces where they've done the math and figured the cost of parts replacement is offset by the savings of the cheap ammo. Personally, I run nice ammo through guns that're important to me, and use the cheap shit in things I plink with or I wouldn't be too worried about having to replace an extractor or even a barrel.

>>31331033
>misogyny

1.5 keks

>>31331046
Mostly, yeah. The math does change on certain guns that have pressed barrels like AKs because the replacement isn't so simple. But that's the bi-metal jacket and not the case.

>>31316919
No.

>>31331097
Yeah, that makes sense. I don't have any AK's yet, and I've swapped a barrel on an AR upper before, so I'm not scared of it. As for things like the RIA 1911 I had, I fed it the cheapest shit on the shelf for a year before trading it.

The only issue I've ever had was when shooting them from my S&W model 66, they would expand a tiny bit more than brass cases. This would make it hard to eject them from the cylinder. Mind you, this was back in the 80's so your milage may vary.
