Not too difficult, Fumbler.

Regarding the rim lock of a semi-auto action and a rimmed case.... It is more difficult to deal with than non rimmed cartridges; however, the BREN gun and the SVT rifle series have shown that rimmed cartridges can be used in auto loading firearms if care is used during loading of magazines.
 
Hmmm... How about a scaled down Model 8 or 81 in .357, takedown, 5-shot. As an option maybe .38 super, 9 x 23, etc...Nice receiver sight, 18" bbl, keep the weight down around 5.5 lbs. Completely useless, yes, but cool anyway.

Yep, also the Mosin-Nagant, SVD... I alluded to that in my first post in this thread. Battle rifles that used normal box magazines and rimmed cartridges were loaded with stripper clips that automatically aligned the rims. People today don't use stripper clips and don't even read the manual, they'd just assume the gun was broken and return it.

Um, why? The M1 Carbine already fills that niche nicely. It is a proven design, is cheap and easy to find, and both 15 and 30 round mags are plentiful. The .30 Carbine round it is chambered for has a 110 grain bullet leaving the muzzle at just shy of 2,000 fps, for a muzzle energy of 967 ft-lbs. The .357 magnum round uses a heavier bullet (125-180 grains, typically) but at lower velocity (around 1,500 fps). Using a rifle barrel to maximize velocity, a typical .357 round would generate about 960 ft-lbs of muzzle energy, or just about the same as the .30 carbine. As range increases the .357 will retain energy a little better due to the heavier bullet, but it will also drop more. At 200 yards (the max practical range of both cartridges), the .30 carbine is packing 373 ft-lbs and the 180 grain .357 magnum is at 385. Again -- too close to call.

So why reinvent the wheel by trying to rejigger it for a rimmed revolver cartridge that offers no practical benefit?


Well............... I'm loading 158 grain JHC 357 for my carbine and they are clocking 1828 FPS with 1172 FPE at the muzzle using 18 grains of Lil'Gun. At 200 yards there is still 542 FPE. The 30 carbine doesn't come close.

You're using handloads. I was citing standard factory loads. Big difference there. With handloading in the right firearm, you can also up the power of the .30 carbine.

Of course, the next question would again be ... why? If you want a semi-auto just a little hotter than a .30 carbine, just move up to something in 7.62x39, like a Mini-30, SKS or AK.

First of all, the 7.62X39 and .30 carbine are not pistol cartridges the .357 magnum is. There is a huge amount of .357 magnum handguns around, there are only a handfull of .30 carbine and 7.62X39 pistols. Secondly the ballistics of the .357 is better out of a rifle than the .30 carbine in every way, there is also a much larger variety of .357 ammo than .30 carbine and they are comparible in price.

You ask why, well why not? The .357 magnum is a great all-around defensive round, so why not have at least one autoloader rifle on the market? It's just an idea, I don't expect everyone to like or find a specific purpose for it.
 
The Taurus Thunderbolt is comeing soon. Its a pump-action rilfe with a really short stroke in 38/357 magnum and 45 Colt. The word is that the Taurus Thunderbolt will sell for under 400 bucks (!!). Lifetime warranty, too. There is also a stainless version.

(do I want one...hell yeah!)

I think it holds like 14-15 rounds. My guess is that a pump or lever rifle would be more reliable. Would this fill the bill for you?

I dunno about all this mess about rimlock being such a giant pain in the butt. I know it's a totally different scale of size, but companies don't seem to have much trouble making 25- and 50- round magazines for the 10/22, and 22LR has a pretty good rim on it. The Ciener kit for my 1911 comes with stagger-stack magazines that hold 15 rimmed .22LR rounds, and you'd have to be a complete idiot to manage to wedge the rim of the cartrige you're inserting behind the one it's pushing down.

Personally, I think it's a pretty sweet idea, depending on how well .357 and .44 and othersuch perform in carbine-length barrels, sort of like a step closer between pistol-caliber-carbines and rifle-caliber carbines. Call 'em Carbine Caliber Carbines! :D

However, I might be a complete idiot, so watch out.
 
Speaking of rimlock...

I'm waiting for this old girl to malfunction, considering she feeds (rimmed) .38 Special wadcutters like grass through a goose:

I bet there are many more357 owners than 44mag owners and to share a single cartridge would be as valid as it is with lever actions. I would buy one.
 
I have a S&W .357, and I like the .38/.357 versatility. I'd like to see a carbine autoloader .357 mag for sharing ammo.

Concerning lever-action .357 carbines: who makes a good model, and what should I expect to pay?
 
A semi-auto 9x23mm Winchester would make lots more sense...

The 9mm Winchester Magnum would be perfect for this application. Too bad it never caught on....
 
Just keep pulling the trigger six times, reload, repeat. This one's in .44 Magnum, but a .357 Magnum version isn't out of the question:


AWESOME!!!

But I would be worried about finger damage, OUCH!
 
The handgun calibers were used in lever guns to maximize long range potential and the gist of the article said that for under 100yds, deer should drop just as dead with the handgun rounds as they do with the rifle rounds.

I don't attribute it to Taylor's moronic arithmetic, but yes, a .357 Carbine is a good deer gun under 100 yards. I'm pushing a 165 grain SWC at 1900 fps out of mine. That's up in the 1300 plus ft lb range. It'll still be up around 800 ft lbs at 100 yards, roughly. That'll gidder dun. I've shot one doe at 80 yards with mine, lung shot, the wound channel was impressive, but not in a .270 class or anything. A good performing high velocity round will do things a pistol blllet even at 1900 fps won't do. All you have to do is clean a few deer shot with both to understand that.

I have a lever gun, 92 Rossi, don't need no stinkin' autoloader. There is a pump out there, Timberwolf, if you can find one. IMI used to market it. The lever gun feeds my 105 grain .38 handload loaded with 2.3 grains of bullseye (great small game round, very accurate) just as well as a full house magnum. You probably couldn't get an autoloader to do that. Autoloaders lack the versatility and kill one of the reasons I like the combination.
 
I'm surprised to be the first in this thread to bring up a dedicated .357 SIG semiautomatic carbine. Much more sensible than trying to self-load a long, rimmed sixgun cartridge like the .357 Magnum. Closely similar ballistics to the Magnum with 115-125 grain bullets.

(There was passing mention of a .357 SIG Mech-Tech pistol conversion above.)

I'm not much interested in .357 SIG handguns, but a Beretta Storm or similar lightweight, modern carbine in that cartridge would be sweet. It shouldn't be much harder than making a carbine in .40 S&W, and there are several of those.

Make it take 15 round pistol magazines and a lot of people will adopt it as their home defense / ranch gun.

It'd be a self-loading, mag-fed, Marlin 1894C. How awesome would that be?

PS: Put good adjustable sights on it too please.

Why couldnt a magazine be built that would be similar to the magazines on .22lr pistols where you have to feed the rim through a slot cut in the feed lips. Wouldn't that alleviate the problem with rimlock by preventing the rims from being pushed behind the one under it.
 
Don't see why someone hasn't thought of it before, all you need is to design a rimless .357 case, and a rifle to go with it. Oh and magazines. Oh and make sure you don't load 357 "carbine" into a revolver. Wait then it becomes a different caliber, doesn't it. Hmmm.

Not in a rifle, I'm betting. The sig round uses faster powders that wouldn't be appropriate for a long barrel and doesn't have the case capacity for the slower, bulkier powders a .357 can shoot. The Sig can't even match the .357 in a pistol with a 125 grain bullet let alone a 158-180 grain in a rifle. I can push a 125 grain bullet to near 1600 fps in a 6.5" Ruger Blackhawk with 18.0 grains of 2400. In a rifle, I can push a 158 grain bullet to over 2000 fps with Lil' Gun. You ain't gonna do that with a sig case, just ain't gonna happen.

But, back just after the turn of the 20th century, this was thought of, old hat, been there, done that. It was called the .351 Winchester Self Loader....

Sure, and the M1 Carbine's not far off either. But neither of em comes with a Picatinny rail (though you can add one to the M1 Carbine). And it's a lot easier to find clean, current production .357 SIG ball at the store than .30 Carbine, let alone .351 Self-Loading.

Put it in a durable "tactical" package and it would sell. Ballistically, 124 gr bullet @ 1600 fps from a 16" .357 SIG carbine should be easy to achieve with standard ammo, maybe 1650 fps, and that would be a nice boost.

Ooh, how about a folding stock!
