Has anyone rechambered a 9.3x57 to 9.3x62? I’m hoping to convert a husqy m96 sporter ( think it is a 46?) to 9.3x62 to clean up the chamber.

If you have done it: who did you use? (BC and AB pref, I generally use corlanes but I’ve moved from that area and though they do good work I might as well send it to a “ Mauser guy” if it’s being shipped.

And: did you have to do a lot of work to the mag box etc?
 
If it is built on an M94 action (often confused with a M96) , it is a M46. The ones built on a FN98 action are M146. I used to own the former and now I own the latter.

You will probably find that the magazine of the Model 46 is not quite long enough to handle some 9.3X62 ammo. You may be able to obviate that if you reload and sit the bullet short. Some M46 have been rechambered to 9.3X62. So, it is doable, but not ideal. From a cost perspective, you would probably be better off selling the 57 and buying a 62.

Why do you feel the need to clean up the chamber?
 
In support of pacobillie's post, I have a STIGA 30-06 rifle here. So was made from an M94 or M96 Swede receiver - probably M94 because of the turned down bolt handle. The magazine box was opened at the front and made longer. The receiver area at front of magazine slot (behind the lower bolt lug recess) was opened up to fit, and to feed 30-06 length cartridges - the key, though, for me, was that the assembly was then proofed, which establishes there is no problem with pressure from standard 30-06 loads. I was not able to discover anywhere in Canada to get proof testing done. From this CGN website, was also confirmed that the throats in those STIGA rifles are unusually long, again, a known technique to bleed off breech pressure that the receiver and bolt get exposed to. So, those modifications to make a 30-06 length, could also be made to achieve a 9.3x62 length. And then the magazine well in the stock also opened up. The same bottom metal is used, although the fixed magazine box was extended. My own choice for a 9.3x62 is a Husqvarna based on a commercial FN Mauser 98, with the solid left side wall - I believe Husqvarna marketed that as a Model 649, although it also might be a Model 640 - there are no model markings on it.

For whatever reason, it appears Husqvarna made various models of rifles using both the M96 small ring receiver and the m98 large ring receiver, but sold them with the same model numbers. I do not know why, but similar to the Swede military that did not distinguish between M38 that were converted from older M96, versus newly made M38 rifles - all were "M38" to them.

The main difference would be the original M94/M96 rifles were "#### on close", although some might be able to be converted to #### on open with after market parts and creativity. The ones based on the various 98's would be "#### on open" - is apparently an important distinction to some users.

Follow-up - I have a number of 9.3x62 cartridges loaded up with 250 grain Accubond - appears I decided to load them so the case neck mouth is at the lower edge of the cannelure on that bullet - do not remember why. None of them will fit into any of the Swede 96 sized magazines here. No reason at all that they could not be seated deeper as needed, with associated adjustments to the load?
 
For me at least, the 9.3x57 M46a sporter I use has all the performance I need for me uses. Norma brass ain't cheap, but I load mine with hardcast boolits at
14-1500 fps at near black powder pressures to ensure long case life.
 
Yes it is actually a 94 or 95 or something or other. #### on close Swede Mauser of some kind

I almost got rolled by a silvertip grizzly last week at work and I want a light gun. I spend all day walking up and down 30 degree slopes covered in blowdown. I didnt want this to become a bear defence thread full of guys who go hunting in whatever northern town will have them one week a year


Also no one wants to buy my 9.3x57 on consignment and I would rather make it useful again than give it away. What makes me want to clean up the chamber is it’s sloppy brass destroying chamber


PM thanks for checking that out with the test loads, good info as always

The #### on close thing is hyped up so much I went into it thinking it would have the lock time of a musket. I can’t tell any difference and I like the action

Most of them have long chambers. To addresss this, i make brass from 30-06 and I size them just short enough for a crush fit. It prevents brass from stretching when fired.
 
Yes, I have already sold my dies and brass. Honestly I reload for necessity not fun, I have neither the time nor interest in that, big thread in the reloading forum detailing my saga if you are bored and want to share your knowledge
 
I wish that I could help more. 9.3x62 was a creation by german guy Otto Bock to sell to German farmers/settlers to Africa colonies who probably needed an inexpensive rifle to handle big stuff like most Canadians never meet - lions after their cattle, rhino wandering through their farm, elephants in the farm orchard. So, 9.3x62 throwing 286 grain softs and solids seemed to work from the GEW 98 actions of that era. If you were British in that same area, and time, you like carried a much more expensive 375 H&H - yet the performance difference is actually miniscual. Modern powders, etc. do stuff that could not be done prior to WWI - so I suspect today's 9.3x57 could approach the old school 9.3x62 with similar bullets. Might be worth to consider - if dealing with silver tips at spitting distance, who really cares about what the expended brass looks like?

^ I was wishing that I had not sold the dies and brass, could just load up the load I had regulated to the sights to and carry it unt I find a shorter gun in a similar caliber. The only other big game rifle I have at the moment in a good caliber is too heavy for this
 
We don't get silver tips in Manitoba, but some decent black bears are here. My back yard last October 5th. I took the pictures with cell phone in my right hand - had a loaded up 9.3x62 mauser in my left as I stood in garage doorway. Bear wanted those choke cherries - that was okay with us - was concerned our old dog would head on out to protect my wife - dog would have got ass kicked. We really liked that dog. Apparently dog's Momma did not raise stupid pups - all was okay after bear had its fill - no shots fired.

But I think the 9.3x62 with 3x Leupold was about best that I have for a 60 yard and closing shot - was those 250 grain Accubonds. Not really an urban situation, I am sure...

Sounds smarter than my neighbour’s husky that charged after a similar sized black bear doing the same thing and brought him right up the hill at me

Wife looks impressed in shot two hahaha I know that look well
 
Haha! "that look" - wife started out in that far corner of yard doing yard work or something - her discussion with that bear as it came up from the lake did not go well - why she was there up near garage - she is not used to losing those kinds of discussions - "to whom does what stuff belong to" - then, dog had to get involved. Was close to a gong show, I guess, but I was holding a loaded Mauser, so all should have been okay???

1905 for the 9.3x62 1912 for the 375hh ... up to the 60s when ammo expired and vanished the 9.3x62 was the real king in africa then 375hh become democratic with the help of winchester and brno and later the zastava. the ones that used enough those calibers cannot make a difference on killing animals.

the original 9.3x62 bullet weight and speed was 285 grains and 2150fps now you can find way faster and you need good bullets and avoid the real soft ones ...

seems that in canada a lot of users are happy with that caliber and there is not reasons for not of course. im of one of those. we have at least 4 9.3s ...
