Hey y'all,

Hope you are all well.

Just wondering could one rechamber a .43 mauser bolt action rifle (no box mag), to .22 magnum?

Thanks for viewing.
Be well.
Best regards,

Rechambered? An 11mm barrel cannot be rechambered to .22. Or converted?

A .22 barrel would need to be fitted. Or the original barrel could be drilled/reamed out and a liner installed.
The bolt would have to be altered to incorporate a rimfire firing pin, and provisions made for extraction.

Martini-Henry .450 rifles were converted to .22LR

It could be done. It would be a challenging undertaking. I have converted .303 rifles to .22LR by lining the .303 chamber and barrel, converting the bolt to rimfire and fitting an appropriate extractor. The Israelis converted 7.92mm K98K rifles to .22LR.

So yes, it could probably be done. And unless you did it yourself, the cost would be substantial.
 
I sold one at the two day Chilliwack gunshow that had been converted to 22LR.

If you didn't open the bolt and look at it, you wouldn't know it had been done.

The barrel insert was only about 25cm long

The bolt face/extractor/firing pin all have to be altered for the 22rf, not a small or cheap project.
 
Training versions of various service rifles were made up in .22 rimfire. As mentioned, I have converted .303s. Posted threads on CGN about faux CNo. 7 and No. 2 Mk. IV clones. There are instructions out there on how to convert a US Springfield originally in .30-06.
I've thought it would be fun to make up other conversions, starting with spoiled rifles. How about a .22 Mosin Nagant?
This 11mm Mauser conversion would certainly be an interesting project. .22WRM would be an additional complication - strictly speaking the bore dimensions are a bit different from a .22LR's.
But the cost of having it done by a professional gunsmith would be significant. Not only must the work be done, the 'smith has to design the conversion system. A commercially successful gunsmith has to generate an hourly return that enables him to make a living.
 
Keep in mind that if this is not an antique status rifle to begin with like a Mauser 71/84, it will not become antique class after this modification even though it would qualify otherwise. We could argue this but this is a view held by the firearms program at this time - your call if you want to treat it as an antique (e.g. not obtain a transfer reference if selling) and then have to argue this in court.

A Mauser 71 would remain antique, yes.

Your 22 mag liner can have an offset bore so you won't need to mess with the firing pin. _uck, for _hits and giggles you can probably do a double bore 22mag off the same firing pin (though it would need to be modified to two prong along the lines of a Swiss Vetterli) - expensive _hits and giggle but definitely unique.

Also consider finding a mauser 71/43 already converted to 12ga - then you can just do an insert that you can install and remove.

Given enough time and money, nearly anything is possible, te question then becomes WHY do you want to do it? Components are available to safely load new ammo for it.

Yeah, I see what you mean [shrug] it's my third language... and now that we are clear on 71/84 not being antique and converting to rimfire not making it antique, back to regular scheduled programming :)
