Discovered yesterday that 32 S&W longs will chamber and fire in a Ruger Blackhawk in 30 carbine. Pressures are obviously not a problem. The round headspaces on the rim and the resulting "POP" is so quiet it almost doesn't require hearing protection. The cases show no signs of anything being amiss except they are dirty.

I have no idea what this seemingly useless discovery is good for, other than doubtless gumming up the chambers. Haven't checked accuracy yet.

Just a bit of silliness.
 
I'm curious as to why you even tried to fire 32 S&W Long ammo in your 30 Carbine?

I doubt it should be done even if only for the cost. 32 S&W ammo costs a lot more than 30 Carbine ammo in most cases. Additionally, pressures can rise when trying to swage down a .314" bullet to .308" although the 30 Carbine develops at least 3x the pressure that the 32 S&W Long does.
 
Let's see. Wrong bullet diameter. The S&W uses a .314" bullet. It's a semi-rimmed cartridge(with a rim that's 15 thou too big to fit at all) in a rimless cartridge chamber that headspaces on the case mouth. So there's no headspace at all. And the S&W case is 370 thou shorter than the Carbine.
Just because something is possible doesn't mean you should do it.
 
I wonder how much damage will be done to the chamber where it is cut to support the rimless .30 Carbine cartrudge case? I can guess with the flame being back in the chamber below the supporting metal lip, and oversized lead bullets being fired and hitting that little shelf, it couldn't take too long before it's rounded off a bit and no longer able to fully support the case mouth of the Carbine case.

Obviously it's your pistol and you may do what you choose with it, but if it was mine that's one thing I wouldn't do.

Stay safe!
 
Based on the logic here, I've ruined my Ruger Single-7 by shooting .32swl through it.(.327mag). Likewise.38spl in a .357mag.
NOT!

I'm surprised that there is enough clearance for the cylinder to rotate with the rimmed case. That would be my only caveat with using them.

The lead bullets of the .32swl will easily be swaged down in the cylinder by the tapered chamber. The fit of the bullet will likely enhance accuracy.
In any other regards, it'll be like shooting.22short CB caps in a .22lr cylinder.

FWIW; my 1943 Saginaw.30M1 Carbine shoots BETTER with a .311" 113gr RFNGC cast bullet than ANY jacketed bullet.
Kudos for trying and expanding our knowledge.

The above has nothing to do with what the OP is talking about. The cases are not similar in any way and they are not even the same caliber!

As I'm sure you know the .357 Magnum case is only a slightly lengthened .38 Special case while the 32 S&W and 30 Carbine have nothing in common.
 
"Discovered yesterday that 32 S&W longs will chamber and fire in a Ruger Blackhawk in 30 carbine."

I have discovered that with moon clips cut from hard but flexible plastic I can fire .380 ACP in a .38spl or .357mag revolver.
I also discovered I could clip a .32 ACP under the extractor hook of an M1 Carbine, carefully guide the nose into the firing chamber, and shoot.*


"I have no idea what this seemingly useless discovery is good for"

Proofs of the old adage "Idle hands are the devil's workshop"?



* [caveat: I do not recommend these practices as normal. Just may be useful to know in an emergency. Normal safe practice is to use the ammunition the gun is designed for and so marked on the barrel.]
 
Uh.... .30 cal is what they have in common!
And no, there is more than just length differences between .38spl and .357mag brass.

.32 is the outside diameter of the CASE as reguards the matter of the .32swl. Nominal bore diameter is .312-.314" with some as small as .308, just like the, uh, .30Carbine... nominal is .308, some say .307" but not in my experience.
Nominal cylinder throats on .357 and .38spl are "all over the place"... Some as small as .354" (Colt Python), or as large as .362" (Charter Arms Undercover.38spl.). Cylinder throats, especially.

If it doesn't fit, you must aquit, .... but in this instance, it just happens to FIT...
Ever look into a .38 or .357 cylinder? They have a restricted section called the "throat". Common procedure for selecting a proper bullet sizer die for shooting cast bullets is to measure the throat of the cylinder. Optimal is .001" LARGER. With the .357mag, it's .12" deeper. Keeps the .357mag from chambering in a .38spl cylinder.

ArchAngel, you know better!

You natty nay Sayers need to spend more time on the range, and in the reloading room, (with accurate calipers) and not so quick to jump on the key board and embarrass yourself.
btw, my .327Fed actually shoots pretty good with .308" jacketed bullets (.30Carbine 110gr RN) but shoots shotgun patterns with .309" lead.

And we won't even talk about the bore choke in my Ruger S7 that I'm still trying to lap out a little at a time.

I wouldn't do it, but likely worst thing will be lead build up on step for the case mouth of the .30 carbine.
 
First - Sunray, where did the idea that a 32 S&W revolver round is SEMI-RIMMED come from?

For decades they have made cartridge converters to allow use of 32 ACP in any of several 30 caliber rifles. I have never heard of one blowing up by forcing that .314 bullet down that .308 barrel.

Years ago Ruger made a limited run of Blackhawks in 32/20, using .308 barrels. Contender 32/20s also use .308 barrels. I've yet to hear of a problem.

When Ruger first started making Mini 30s, they used - yep, you guessed it - .308 barrels.

This appears to be much ado about nothing.
 
I once fired 3 .357 mag jsp through a 30-30 I didn't look close enough and have two lever action that look pretty similar. It fte on the third round then I noticed the case was ruptured and blown out. Scared the crap out of me when i realized what i did. It didn't hurt the 30/30, but it could have blown up on me.I did have some copper fouling to remove.
 
Sorry to think that firing a completely incompatible round into a chamber that head spaces on the case mouth rather than on the rim MAY cause damage to the supporting portion of the chamber for the rimless case and is a stupid idea there sirs, even if the bore diameters are fairly compatible. If it was a post apocalyptic "Road Warrior" necessity the idea may be ideal. Since it isn't, playing caliber-compatibility roulette just for kicks is asking for unnecessary trouble.

Apparently those others who agree that it's a dumb idea are also shipwrecked and lost out on ignorant island.

I'll just stick to using the rounds that my firearms are chambered for...
 
Obviously many here don't understand that a Ruger.30Carbine revolver is a MUCH different animal than a .30 Carbine semi-auto rifle.
.30Carbine pistols are noted for vicious muzzle blasts, and mediocre to poor accuracy, depending on ammunition choice.
Noticing that the very mild .32swl can be chambered and fired is a note worthy discovery.
Being able to shoot mild, very economical, pleasant, and useful load in what is generally looked on as a near useless firearm is benificial. Until only very recently, I could cast, load, and shoot .32acp, .32swl, and .38spl for less than the cheapest (but unavailable) rimfire.

Sorry rio, my parents were from the Great Depression generation, and also WWII. I too know what it's like not being able to go to a big boxstore and get whatever is your desire 24/7. Or a 7/11 on every street corner.
I was only mildly affected by the Obama-ammogeddon. 50,000+ primers, several tons of scrounged scrap lead, and several decades of picking up discarded brass cases at a public range stood me in good stead.
Those of us out here in "fly over country" have experienced "doing without" and knowing how to improvise can mean survival.
It's happened before, and will happen again.
Not a "prepper", but a cautious "hoarder", maybe...

The soft lead used in 32 S&W long isn't going damage anything. I regularly shoot .311 lead bullets in .30-06. It's easier to size lead down .005 than it is to size a copper jacket down .001.

Other than the potential for headspace problems and the cylinder binding, my biggest concern would be that the brass would be ruined due to the tapered .30 carbine charging hole, but that's not a concern unless planning on reloading.
 
Goose, our lineage isn't all that different. I came from a family of "rural electrification project" beneficiaries who ranched many acres in Central Texas for ages, crossed with Scottish hard rock miners who immigrated to the US in 1910. The adults in that clan worked in the gold mines while the kids were in the stamp mills of Searchlight NV mixing mercury with ore to extract gold. No one in my immediate family was/is wealthy, and we all know about improvisation and making due with what we have on hand. My wife and I have worked very hard to have a lot more than we ever thought possible, which allows me to indulge in the shooting sports far more often than most folks. I certainly didn't inherit it, and like you, I earned it.

I am very familiar with the Blackhawk .30, and with the .30 M1 Carbine as well. Yes, the pistol is an unpleasant beast when fired with rifle-spec loads, but it can be tamed with a load of around 3.0 gr of Trail Boss and a 100 gr Speer Plinker (or similar bullet). This makes for a load perfectly suitable for the Blackhawk that serves the purposes of the original poster, and leaves nothing to chance.

As for not having the opportunity to purchase or experience things, you in flyover country need to thank the Lord every day that the liberal rodents who infest the Statehouse here in CA aren't in your Statehouse. Trust me, you would be singing a completely different tune when it comes to firearms laws and regulation. Easily 2/3 to 3/4 of the guns reviewed in magazines today aren't even legal here...and come Jan 1, 2018 I won't be able to ammo buy on line... and I will need a State-issued permit to buy any ammo at all. I guess if I haven't been reloading for decades myself the .45 Super, 6.5x55, and .41mag I own would go hungry, as none of my local retailers stock those calibers at all.

My issue in this thread revolves around people being encouraged to experiment with firing cartridges that are not designed for, nor even remotely compatible with, the caliber of the firearm being used. We have all seen what happens when a .380 makes it into a 9mm, .40 is fired in a .45, a 44 mag slips into a .45 Colt, etc. Sometimes it's a 'pop' and a gun merely jams as the case ruptures in the chamber, sometimes it's a "kaboom!" and a trip to the hospital for the unlucky or inattentive shooter when the gun explodes. Yes, I have seen all (and more) of these caliber mix ups occur, and total failures aren't pretty. ( The .44/.45c resulted in just a burst case and some powder freckling of the shooters face and hands because the gun was a first model Vaquero .45C that contained the full house .44 mag pressures. If it was a Peacemaker or clone it would have been a disaster.)

Sometimes these things work without issue and no one is the wiser. Sometimes they don't, and that is what we as responsible shooters need to discourage. I opined that this also may damage the gun needlessly as well. If it does or if it doesn't it's not my gun, nor will it ever be, so I will truly never know. But even if the chamber isn't harmed by firing the .32 SW in the .30 Carbine revolver it is still not a smart thing to do.

We shooters take enough grief from anti-gunners who take aim at those of us who still embrace our 2nd Amendment heritage, and every pathetic a-hole who shoots up more innocents ( ala Las Vegas ) makes it even more likely a future unfolds where my kids and grandkids will only see a gun in a museum or in the movies. Adding to it people violating a solid tenet of firearms safety, by firing cartridges through guns that were not chambered for or designed to shoot them, is just another chance for a needless injury to occur. (Which naturally leads to the requisite fodder about the dangers of gun ownership for the antis to trumpet).

Keep on keeping on, and stay safe!
 
Wow, I seem to have really created a firestorm of controversy here. Let me begin by saying that I am retired, and like many retired people I have too much time on my hands, which is spent discovering useless bits of information. Like finding out that .32 S&W long ammo can be fired in a Ruger 30 carbine revolver. Is it practical, useful information? Uhhhh....No. No more so than the fact that the same .32 S&W ammo can be fired in a Nagant revolver, as an alternative to the hard to find Nagant ammo.
Like I stated, this is pretty much useless information, but there is nothing unsafe or dangerous about it.

It is no more than simple silliness, but us retired old buzzards thrive on that kind of stuff..... Think I'll go see if any degree of accuracy can be obtained while engaged in this silly activity.....
 
The S&W uses a .314" bullet. It's a semi-rimmed cartridge(with a rim that's 15 thou too big to fit at all) in a rimless cartridge chamber that headspaces on the case mouth.
The 32 S&W cartridge is a rimmed round. And that rim headspaces the cartridge just fine in the carbine chamber. I think you are confusing the 32 S&W round with the 32 ACP, which is a semi-rimmed cartridge.
 
I wonder how much damage will be done to the chamber where it is cut to support the rimless .30 Carbine cartrudge case?
how much damage is done to a 357 chamber firing a lead bullet 38 SPL round? After close examination, I see no harm to the chambers other than the usual gumming up after firing a shorter round in a longer chamber.
 
Moon clipped 45acp's with .451" bullets run just fine in a 45colt revolver (albeit none-too-accurately most of the time) like the 45 acp/colt Redhawk, or a milled 454C Super Redhawk. Plenty of guys feed these same revolvers with .454" lead bullets as well. Of course, you're talking about a base diameter of .476" for the ACP, and .480" for the Casull, but it sure doesn't seem to cause any issue.

Anybody else remember the "chamber inserts" to allow use of x39 ammo, complete with .311" bullets, for use in .308win and .30-06 rifles? I've heard, but not seen advertised, these have made a resurgence in recent years due to interest by the "prepper" crowd...

There are plenty of 9mm/357mag convertibles out there, running .355" bullets AND .358" bullets in the same revolvers without issue.

I've seen guys who have ran 22LR in 22WMR revolvers for DECADES, almost never actually firing a mag cartridge - often with the passive acknowledgement, "eh, every now and then one splits, but they all eject fine, and the chambers look fine. I'm not reloading 22LR, so who cares what the case looks like coming out..." Frankly, after witnessing this for DECADES, I'm not averse to the idea myself.

So now we're complaining about running .312 -314" lead pills in a .308", with a fantastic pressure ceiling, firing a 12,000CUP round in a 40,000 compatible chamber...

Guys get all up in arms about this kind of thing, but I can say this is much less of a stretch for me than what I've seen done by others...
 
I love 32 SWL revolvers in the true 32 size frame. Now strangely during the recent panic I usually could find a box or two of 32SWL ammo at stores. Now the shelves are full agian but no 32 SWL. 32 ACP which is in abundance goes bang in my 32 SWL wheelguns. Now it is not going even be put into my 32 S&W not long topbreak. One of these days I am gonna to rechamber my Nagant to 32-20.
 
This sounds like the kind of thing where, if I did it and got hurt, I would have no one to blame but myself, and that's how everyone else would feel about it.
