.41 Mag Single Shot

[Good Cheer]

Surplus rifles...
Have any suggestions on a model of mil surplus rifle to turn into a single shot .41 Mag?

[Texas by God]

Carcano comes to mind. Maybe a 91 Mauser. I'm picturing this in my mind and the extractor on these would seem to work better to snap over the .41's rim. Lifetime .41 Mag fan here; I like how you're thinking!

Very interesting project. I'd like to do the same to have a platform for testing accuracy of ammunition.

[Marlin356]

Any rolling block would work fine with extractor mod.

[BK7saum]

Not a single shot but I've considered a 41 mag on a 91 mauser with desert eagle magazines. Dont know if I'll ever get it done, though.

I'd love to have a .41mag long gun that wouldn't rape my wallet.

No.4 or SMLE.
Go whole hog and do a Delise type conversion sans suppressor tube.
The receiver can be relief cut to allow a larger diameter breech for the more powerful cartridge.

A friend told me of his plans to convert a SMLE to .45 Colt revolver (Long) cartridge.
The Delise type conversion is suited to most large bore revolver cartridges.

I've seen a Mauser Model 1893 converted to shorter cartridges by cutting and welding the action rails and shortening the bolt. The bolt was shortened by first cutting then counter boring one end and turning down the other, then silver brazing the two together. Made a neat package.

Some day maybe a super cheap No.1 in 9.3 will appear and need to be rebored.
Or a 1885 in 38-55.
Or maybe I should give up on the 6.5x53R (wipe tear from eye) and make it a .41.

Sent a letter to the Winchester that basically said I want a .41 Mag 1885, how much?
In reply I received an envelope with their catalog which is a photo montage of "cowboy" action shooting lowest common denominator garbage. Not a word about what I asked.

Cross Winchester off the list.

[LUCKYDAWG13]

not a Surplus rifles but i think a Contender would be the way to go

Recently got me a Henry Big Boy Steel in .41Mag (16" barrel with the large loop), I know it's not an 1885 but it may scratch an itch, I finally was able to shoot it for function and it didn't disappoint, now to change the rear leaf for a Skinner sight and it'll be a good shooter.

No joy. Green Mtn doesn't make 41 caliber barrels.
Cue Debbie Downer music.....

JES Re-boring does .41 barrels, and they convert 336 Marlin 30-30s to their proprietary 405 JES caliber, which is the same as .41 mag barrel. I wonder if they chamber the .41? I don't think the 30-30 will ream out to .41 mag, but maybe there's another contender.

A octagon barreled one would.:grin:

i would vote for a military rolling block, new extractor and barrel fitted to it!

[Good Cheer]

When I lived in SLC in '81, the fellow running Ackley's place had done one '94 conversion to .41 Mag.
Told me it took so much work to get it to feed reliably that he'd never do another one!

[Texas by God]

A Ruger #3 in .22 Hornet or .223 would be a great .41 mag JES rebore. If he chambers for it, that is.

Good morning
Basically did this about 6 years ago with my desire to have a 414 Supermag lever rifle to go along with our Dan Wesson 414 SM.
If you do a search here for "Marlin 336 414 Supermag" the details will pop up.
The shorter 41 mag case will require some work to be done on the lifter. A longer cartridge stop is needed to position the round closer to the chamber. Then depending on the rim guides they may need altered to get better up flow level with the chamber.
In the end... get the Henry. Right out of the box you have a 41 mag that feeds and shoots and will cost a bit less. Plus it weights less.

I got one of the first 250 that they made, but it's the 20". They said they weren't going to make the 16" version.
Guess they didn't realize how many they would sell. (Wonder how many?)
Shoots greater, finally got a scope mount, and scope on it. Going to work up a couple loads for hunting.
Then may do like you and put a peep on it.

The answer is to buy a used 1885 Pedersoli and reline it to 41 mag. I just did one in 44 Ballard extra long that uses 44 mag brass and B/P and its a hoot.

[Brassduck]

+1 that is a plan

[303Guy]

Being me I would use a Lee Enfield action. I'm sure it would work as a single shot with no mods at all. It might even feed from the mag. One trick is to use a mag with no innards. Spent cases just drop in - very handy. But then I would probably use 303 cases to make a 41 wildcat which would be longer and capable of more power or operate at lower pressure. But I digress.

On the other hand, I have this 410 break action shotgun that would be real neat in 41 mag but it's not a milsurp.

A .410 chamber would be too big...I think they are .45

[Blanket]

Would look at a Savage 340 30-30 action for a base. You could modify the mag possibly and have a repeater and they are cheap

I never thought about these.....thanks for the idea.

[303Guy]

So just being curious I checked to see whether a 41 mag would work in a 303 Brit. It seems that it will. Funny enough, a 7.5x55 Swiss will work too - it has the same base diameter as the 41 mag at .490. Short cases tend to drop out before reaching the ejector pin or whatever it is called. Not a problem if the mag is not in place as the cases will just drop down the mag well or flip over the side. I was playing with an unbarreled action and one of the cases was a very shortened 303 Brit case.

[Texas by God]

The problem I see is a lack of .410" rifle barrels or liners at a good price for this project.

Kinda had to roll their brass receivers around in my mind a bit because they would have the added benefit of providing a little resistance to corrosion from any black powder blow by.

Would .40 S&W carbine barrels work?
Don't know much about these but have noticed there were some made by various makers.

The side mounted flat spring with stud running through the action body wall as used on some sporting rifle conversions should work. I've seen these for cartridges as small as the .22 Hornet.
A more neat commercial conversion used a flat spring with blade turned 90 degrees that rode in a slot milled in the body.

Whichever method is used the ejector would have to be properly beveled and polished to avoid hanging up on the forward stroke of the bolt.

[303Guy]

I guess that for me a straight wall full length case would be the answer. Seating the boolit deep would help reduce case capacity.

A 22 hornet on a Lee Enfield action?. Have barrel, have action .... [smilie=1:

Trouble is, I already have a perfectly good 16 twist hornet that shoots boat tail 55gr sub-MOA at 2740 fps. Aah, but I need a cast 22 hornet! Which all I can use a 22lr barrel for anyway. I found a way of casting smoothside boolits for the hornet - 55gr RCBS swaged. (Off topic. I know - my apologies ).

But back to topic, I like the idea of a 41 mag single shot and would be what I would do if a barrel came my way. I have a plan to use a separate chamber screwed onto the barrel so as to be able to turn the chamber on a lathe without the use of a reamer. I would probably use a shortened Brit case though, using the same lathe set up to make the case former as the for the chamber.
