Rebarreling a mauser 93
has anyone changed a 1893 mauser to 7.62x39? I read a blog some where that the writer talked about changing a Spanish 93 mauser to 7.62x39. I have a 93 in .308 which is not safe to shoot I am told.
How hard would it be to change over? Thanks in advance. Steve

Depends how the barrel is shaped at the breech end. You would have to set back the chamber so you could put a correct one in which means cutting off maybe a inch at the back and moving the threads forward. If the barrel has the normal Mauser style flange in front of the receiver, you will need a new barrel. If the barrel is contoured more like a sporting barrel, there is probably enough metal there to move the threads.

I thought about using a take off barrel from a 30 cal to rechamber in 7.62 x 39.Gun Parts sold a conversion in the past,I waited too long and it is discontinued,but they still sell conversion kit for the mag. I will be picking up a rifle with the kit installed in a couple of days.

Regardless of what you've been told about 308 rounds in the M93 you have it only applies to some of the factory or military loaded ammunition you might run across. Properly handloaded it is more than safe and strong enough for shooting and hunting, as long as you use a little bit of good commen sense.
Now, as to the 7.62x39 and the barrel you already have, well most liky yes you can rechamber it, but you should check out your rifling twist first and make sure its a good match up. However if you'd like to try things out first with an adapter or even use it as a long term conversion here's a link for you.
Scroll down untill you find it under "adapter's".

What about rechambering to 300 savage? Lenght is close, pressure is close?
Hmm. I guess the bore is diffrent... What about a 300 blown out to 7.62?

Local outfit, see them at some of the gunshows..
Bought a couple adapters, they work,
They even make a few they won't warrenty due to thin walls, Like 30-30 .30 Carbine.

If .308 is safe
Then ask hom or her this question.
I have changed 2 mauser 98's fron their current calibers to a 7mm-08 and a 243.
As long as it has the same bolt face it will work.
But check with a gunsmith where ever you live to make sure.

308 to 7.62X39
When converting to 7.62 mm X 39 the big problem was the extractor. You will have to build up and re machine the extractor or grind relief on the bolt head so the extractor will hook on the case head.

Rebarreling a mauser 93
I have rebarreled a 98 to .243 and a savage 110 also to .243(easy). Going to 7.62 x 39 looks much more difficult, maybe more than I am up to. I know from past post that this is the place to goto for answers without being flamed. Steve

Picked up mine and it looks good.I ordered some Winchester FMJ ammo to test fire it and mounted the bases and rings for the scope.The bolt handle is going to hit the scope, even though it is bent from the factory, so it will have to be altered.Nice little gun,I hope it can hit the broad side af a barn from the inside!

If it's in good shape leave it in 308. The '93 and '95 may lack a few refinements of the '98 but they aren't "weak" if used with sane loads. My '93 in 7x57 has digested many stout loads with 160 gr bullets with no porblem. I wouldn't try to turn it into a 338 Superwhizbang tacitalelitemagnum but it's a good safe action.

Sure a 93 or 95 in good shape are safe for 7X57 mm, they after all were made for that cartridge. However, a .308 Winchester is not a 7X57mm and just because someone rebarreled a 93 or 95 to .308 and has fired hundreds of rounds with out failure DOES NOT MEAN THAT IT IS SAFE! The 98 has a much better system to handle a ruptured case plus the flange on the bolt shroud directs gas away from the shooters eyes. Not so with the 93 and 95. It is not worth risking you life or your sight.
People have rebarreled those Russian Nangets to 30.06 and got away with firing a few rounds. That is even a more unsafe thing to do. Gary P. Hansen

Had a long reply and lost it. Short story- a fool can blow up ANY gun. The 93, 95 and 96 are safe used with sane loads.

I have had a number of FFLs. I have written for, The American Rifleman, Guns & Ammo, Rifle, Guns, The Shooting Industry, Gun World, Gun Digest and others. A 93 or 95 in .308 is not safe to shoot even with factory loads. The action just was not designed for that type of presure. I am not the only gun writer who has said so. If I remember right even Mauser said it was not safe back in the 60s or 50s. The bolt will most likely "setback" causing excessive headspace and causing a problem opening the bold after fireing before the action or the bolt fails but you can not count on it. Every time a 308 is fired in a 93 or 95 the action or bolt is one round closer to failure because of work hardening. I say again, taking the chance is not worth your life or your eye sight. The 7X57 mm is a fine cartridge and is safe in those actions. Now, this is still a somewhat free country, you are free to disreguard my advice if you would like. Gary P. Hansen

Frank de Hass has the same opion in his book "The Bolt Action Rifle".The 7.62x39 should not be a problem.

Pardon me, I am sure that you know more about this than Frank De Hass, Ludric Olson, Myself, the NRA and the Mauser Factory. Please, feel free to shoot all the .308s in your 1893 Mauser that you want! You are most right, nothing bad IS LIKELY to happen and if it does isn't that what they have insurance for. A lot of people get along just fine with out eye sight.
As for your low number Springfield, Please feel free to keep shooting that, also. I am sure that the Army overreacted when they recommended that they all be scrapped. After all there were only 68 accidents, none resulted in deaths and only nine were serious. Out of a million rifles what are the odds of it happening to you. There are other fools who still, to this day shoot their low number Springfields and others who will go on blasting away with their 93 Mauser in .308 .

Sorry, you asked how many Mausers I have spent time with. I have only owned one 93, and two 98s, and four 1903 Springfields. However, I have done gunsmith work and or examined many hundreds of them. Gary P. Hansen
