You've almost got it. If it can fire 4 shots in a row, you know it can be made to fire reliably. A caliber conversion in a mag fed semiauto is one thing, converting it to a rimmed cartridge is a new beast. Worse comes to worst, it will end up in a Forgotten Weapons video. "The mad German gunsmith's M1 Carbine"
It is not a new beast, I have been shooting a Universal ferret, chambered in 256 Win Mag, a .357 necked down to 25 caliber. I really want to convert this to .357
Pay no mind to the haters, my man. This is how progress is made. Some big arms company out there will eventually realize a .357 M1 is viable because of videos like this.
this would be very markettable here in the usa...i love the m1 carbine-- but do not like the availablility ( or the lack of different loadings) for m1 carbine ammo here....357 mag is all over the place here-- if you sold one with a 5 round mag (for hunting legalities in some states) that would really be a great first deer gun ( or a defensive rifle). have you contacted any of the manufacturers here in the u.s. about your prototype?
Tank you very much! Yes, my tenacity is real. When I invent something new in my workshop and got a good idea - I never give up! I go step by step but when it stops I can also wait one or two years until I solve the problem....It is very easy to show a good working video on youtube of each weapon but the people should see that it is not so easy to come to this point. My next project will be my Werle Mini 14 with a short stroke piston from the M1 Carbine.Best regards from Germany, Herbert Werle
Herbert Werle Mini-14 with an M1 carbine piston? Now that's something I would love to see. Good luck with the .357 carbine and all your current and future endeavors!
@@HerbertWerleUse. Coonan 1911 357. Ruger made a Deerfield carbine in 357 those might not be impossible to find. And make modifications to feed these magazines Or develope ur own. Rim lock will be ur enemy. 22 deals with this by using a steep angle magazine. Psl and svt prevent rim lock by only allowing single feeding to load the magazine from from to back.
This is a bit old already, but I also have a M1 carbine, Inland with IBM barrel, and rechambered at some time in 357 magnum. I can load 3 in the magazine and one in the chamber and it is super fun to shoot. Wish I could get the Universal Carbine 256 Winchester Magnum single stack magazine so I could load 5. I will eventually sell this as I am slowly selling my collection anyway, but it is always hard to sell something rare and beautiful.
When it comes to all firearm development, making mags is the most difficult thing to do. When doing caliber changes, it's best to take mags that already work for the caliber and make an adapter for the gun your doing the conversion on.
Hallo Herbert Replace the return spring with a high-speed return spring from sarco inc. This helps with a better feeding of the bolt carrier. A friend of my fathers back in the 1980's, turned a .30 M1 Carbine to shoot the 45 long colt.
Wonderful! Progress. Keep up the good work, Sir. If you would do your comments out loud... maybe subtitles, it would be interesting for us to hear what you're thinking. I think you have a success on your hands. Just a little fine tuning more and you'll be able to go to production.
With the popularity of the .357 cartridge and caliber consolidation I’d absolutely buy a .357 carbine particularly if one was made with a 15-20 available magazine
Hey Herbert, i have one, perfectly working, made in mid Seventies by Armando Piscetta in Italy. He made also magazine, i have one, but the original “model building” is lost. You can also use a Universal magazine, made in the ‘80 for a commercial M1 in different calibers, made by Universal Arms. I’m tryNg to replicate the magazine modifing an original trasforming it in a single cartridge presentation
I see that you have the problem of feeding FMJ nearly sorted out. The trouble seems to be the hollow points. Well what can be said about this, the weapon was only intended to fire FMJ originally. All of the value of an endeavor such as this lies in achieving successful feeding of a variety of hollowpoint ammunition. That is the strength of the .357 magnum round, especially in carbines -- the terminal effect is devastating! Also don't forget to include an adjustment mechanism to the gas system so that economical .38 special rounds can be utilized.
Man, that thing is sick. I've dreamt of a .357 M1 carbine. I adore that rifle but the biggest drawback is the availability of the ammo. It's not very common. Making it .357 is a simple solution to this problem.
Well i saw on one forum that some guy was trying to make some from 223 cases since the case diameter at the rim is the same as the case diameter on 357 mag, so he just straightened out the 223 case and trimmed it down but idk what came of his experimenting in the end or how one would headspace that
9mm Winchester Magnum, Starline makes the brass, since I have an IAI AutoMag III in 9mm Mag, I converted one of my carbine receivers to 9mm Mag, I use regular 30 carbine mags.
Idk why I said pps43. Lol. I meant look as rimmed magazines from Japanese smg and mg. Look at 22 magazines. Coonan 1911. And desert eagle was chambered in 357. Ruger also made the 44 Deerfield carbine with rimmed cartridges. It takes more than swapping a barrel to change any gun. Magazines have to be purpose built.
Hi, you are a gunsmith the only thing you need is a lathe a milling machine, a few reamers and a chamber reamer in .300 Win. Mag. and of course the IMI Magazine in the cal. 357 Mag. First you have to cut the original M1 carbine barrel 3 cm in front of the gas piston, put the barrel in the lathe and ream it out from 30 carbine with the .300 Win Mag. reamer as deep as possible. Then ream it out step by step to a diameter of of 14 mm. Now cut the barrel once more exactly at the first step on the barrel. Turn the barrel around and put the treads now in the lathe, ream it now also with the .300 Win Mag chamber reamer then once mor step by step to the same diameter of 14 mm. Now you have to make an insert barrel with the rear diameter of 14 mm and push it in. Open the bolt face in the same diameter of the .357 mag. rim(milling machine) and cut the now the protruding rim of the bolt face 1.6 mm back (left over the thickness of the 357 Mag rim). Now you have to cut a small amount of material (1.6 mm deep) from the back of the barrel for the extractor from 12 o' clock to three o' clock. When everything is done and you have checked it all glue or soft solder the barrel in but take care for the right glue that you a able to remove the barrel if needed. Don't forget the gashole in a diameter of 2.4 mm! In case you will have more questions - please let me know.
@@drcelsius I've been looking at this conversion, I think it would be easier(if you are a gunsmith) to get a .357 barrel blank, cut the threads for the receiver end of the barrel, then weld the gas/piston block in the proper location. I picked up a .357 timber wolf barrel from either Sarco, or Numrich arms for a song along with a bunch of .30 carbine demilled barrel stubs for their gas/piston blocks. Although, if you look at the Universal Ferret carbine(chambered in .256 win Mag) they have their own unique gas/piston block.
Cool work man but why would you use .357 mag? It seems like an expensive way to get less power out of the M1, I get 9mm since its cheeper than 30 carbine but 357 aint cheep and has a noticeable dip in muzzle energy. Just my thoughts though, definitely cool none the less
E. P You may think not but numbers do. You're getting at least 300fps slower even out of the longer barrel one is a pistol cartridge the other has more in line with a low power intermediate cartridge. And like i said, price is still a pain with this set up
@JeSSEbism No no it can't. If you loaded 30-30 with as little powder as possible to get it out of the barrel then sure 357 is more powerful. 30-30 can have a 150 grain bullet with a velocity of two and a half thousand feet per second and 357 can have a 158 grain going over 1000 fps slower. You couldn't have said anything more wrong unless you said the moon was made of cheese. 30 carbine is a slightly lighter bullet going much faster than 357. There's a reason people debate whether it's an intermediate cartridge or not and don't with the 357
Why not just do a 10MM ACP M1 Carbine and save yourself the trouble? The M1 Carbine was partially inspired by the Winchester m1907 in .351 Winchester, the round which was the inspiration of the .30 Carbine. That round has approximately the same power as a .357 Magnum. The Winchester M1907 was used by Entente Air Crews in WWI. The French liked it.
The .357 Magnum is a much more common ammunition for such a small and handy M1 Carbine and next one year ago I made my first M1 carbine in the real hot cal. 7,62 x 25 Tokarev.Best regards from Germany, Herbert Werle www.waffen-werle.de
Herbert Werle The new Czech 7.5 round represents a lot of promise in that regard. But it isn't common. A rimmed cartridge like the .357 Magnum with the box magazine the M1 Carbine is mated to makes the proposition extremely frustrating. Perhaps .357 SIG?
Das funktioniert ja super. Jetzt ist dass Ding auf egun für 1300€. Also bei dem Video würde ich keinen Grund sehen so viel Geld für dass Ding auszugeben

Vielen Dank Herr Werle für Ihre Demonstration hier. wunderbar. 🇩🇪🇺🇸
you need to market this in the u.s.a. i would buy one

Right now, an M1 carbine in 10mm would sell like hotcakes
How much for a 357 carbine kind Sir? I want to own one of those rifles!!!!
Herbert, I’m amazed by your tenacity and vision! I’m following your progress because i would love to own an m1 in ep.357 too!

What’s the latest on this? With the 158 gr. bullet, what velocity range is necessary for reliable cycling? What about 180 gr ?
I love the mag in a mag concept.... Reliable feeding is one of the hardest things to do when changing caliber of a firearm

This helps with a better feeding of the bolt carrier. A friend of my fathers back in the 1980's, turned a .30 M1 Carbine to shoot the 45 long colt.
The recoil spring had to be replaced often with the original .30 caliber m-1 carbine.
Nice, I always wondered why no one ever made a semi auto .357. Was there any progress on that project?
Keep up the good work, I think it's a noble idea, Bravo!
Wonderful! Progress. Keep up the good work, Sir.

I've shared your joy of accomplishment when it fired the 3 shots in a row.
My best support from France,

Das ist sehr beeindruckend.
Damn! I was just saying I'd love to have a M1 Carbine in 357 magnum, great minds think alike 😆 I hope this works out because I really want one!
Would a rotory magazine work better? Double stack mag, or combination rotory/double stack magazine?
ruger made a rotary magazine for 357 and 44mag for their little known lever actions.
Keep up the good work You are doing
Have You thought about a different spring pressure
I’m working on doing this to an M2 carbine in America. I have a .357 bolt, but I am having trouble with getting the extracter to work. Any advice?
Danke. Sehr gute mein Herr.
Was the short stroking problem from too little gas? Bigger gas port maybe?

Is that a modified Desert Eagle magazine?
Real cool ! Keep up the good work
What magazine is inside? Desert eagle? Coonan used a tilting magazine insert.
I’m going to try using a.256 winchester magnum bolt and magazine. From a ferret rifle.
Why not go for the .357 rimless?

What about the bolt? How did you modify that?
0:52 The boxes are dancing.

3D print a new magazine from the design you made
Meine Meinung: Umbau= Schrott!
I would buy on of these to go with my Blackhawk
This would have beat the nazis faster than the M1 garand lol
I have another idea!! Mini14 and loading 357 bullets into 300 BLK casings for a more rimless cartridge.
300blk uses a 223-5.56 case thats cut
@@constitutionalrepublican1611 Yes, but I've seen people make rimless 357 out of those.
I would try American ammo and low rain and high grain to see what start to work
Pretty cool
Look at former rimmed smg magazines. Maybe a pps 43 mag conversion
