HI,

can anyone tell me please what all is involved to convert a 9,3 x 57 mod 96 husqvarna to cal 9,3 x 62 ?

is it simply reaming & headspacing the chamber.....

or does the magazine box, feed ramp or whatever need to be altered ?

how difficult is it to do ?

your help appreciated. tom

I've never done it so take this lightly.....I would think it's simply rechamber and headspace.

Get a few rounds of 'X62 and see how they feed to verify some of this.

Pretty commonly done in Scandinavia. I have a Stiga 9.3 x 62 on a military 6.5 action. Which is a factory conversion equivalent. They added a little length to the front of the box and widened the feed ramp just a touch because the timing is off with the longer case; the bullet nose hits too far to the side of the ramp. You could be lucky in that the Husqvarna ramp for a 9.3 x 57 is already wider than the 6.5.

Just checked:


Stiga is on the left in the bottom pic; on the right the other two. Notice the bullet-tip cut on the back of the front ring like FN 375s.


Notice how they brazed a steel shim to take up the first stage slack instead of pinning the trigger guard. Then ground a depression until the tolerance was right on the money.



Stiga opened everything up and cut different rails. The other action is a 9.3 X 57 Model 46. Whatever they did, it feeds as well as any rifle I've owned.

Great Pictures, Harry!
thanks for sharing

I have never done this, but I have opened up a few 8x57's to 8-06. What I have experienced is that the old chamber often is a bit sloppy, while the new one I cut is not. Result is that the lowest part of the neck, wich is a part of the old chamber, is wider than the top end, leaving a little shoulder on the neck.

To be sure to avoid this problem, I now always set back the barrel to make sure the whole neck is freshly cut by the new reamer.

Like Tigger says - and thanks for the picks! - magazine needs to be lenghtened a bit, but that should be all.

Good Luck!

thanks guys for all the information. the seller tried a simple test that gave a lot of information.

he put 3 30-06 rounds into the magazine. they went in fine.

then he cycled the bolt - it would pick up the round and start it into the chamber.

ejection was a bit sticky becuase the bullet was still in the case.

so on the mod 96 swede it looks like no alterations needed to mag box or side rails

and maybe only a little on the feed ramp possibly.

looks like it is mostly recut chamber and headspace

Hopefully that is all but I would buy a box of 9.3 to be sure; the 286 gr bullet equates to the 200-220 gr factory 30-06 which is quite a bit longer that 150 or 180 gr loads.

Most 9.3x57's built on 96 actions by Husqvarna have the short magazine box. If you don't want to lengthen the box when you convert to 9.3x62 simply use Norma ammunition. They load the 9.3x62 to fit in the shorter magazine box whereas most others do not.

Sorry to pull up an old thread, but the subject was exactly what I'm looking for. I am looking at a Husqvarna 9.3x57 that was rechambered to 9.3x62. The magazine box was not lengthened. When the dealer was checking, he could only get one round of S&B 285 gr cartridges to fit in the magazine and then chamber. The magazine is just a tiny bit shorter than that particular cartridge. It sounds like handloading and seating the bullets deeper than normal or using a 250 gr bullet might do the trick, but I would like to know how much is involved in lengthening a magazine box. I can't decide how much I would be willing to pay for this rifle until I get an idea how much $$ and trouble will be involved in getting it fully up to speed.

Thanks in advance for any help.

I'm not a 'smith but I have loaded the 9.3 some.

I think you'll want all the cartridge overall length you can get. If you use the Barnes bullets of course they're long anyway and powder capacity is an issue. I highly recommend the Barnes 250g in the 9.3.

I also highly recommend the 9.3x 62. I've had a ton of fun with it.

I just got done doing that very thing, a 9.3x57 to 9.3x62 on a Husqvarna 98 action. It feeds just fine.

And will be for sale as soon as I pick it up from the 'smith and take some pics.
