Re-chambering 9.3x57 to x62

Your project might become fairly expensive if your magazine isn't long enough for the longer cartridge, making it more economical just to purchase a 9.3X62 rifle. Dogleg might chime in with the name of a gunsmith, if not PM him; it seems to me he mentioned someone in the Saskatoon area.
 
It has been done lots - Tradex has some M96's right now that are clearly marked "9.3 x 62 rechambered from 9.3 x 57".

I also own a Husky 9.3 x 57 that I had rechambered to 9.3 x 62 (thanks Supercub!). Works great, cost me $140 locally.

It is slightly shorter than a M98 version, but I mean slightly. Most factory 9.3 x 62 ammo works in it, some maximum COL stuff does not. I don't have my reloading info in front of me right now, but I think my handloads for the converted 9.3 x 62 are about 3.18" vs 3.29" for a factory Mauser 98 in 9.3 x 62. I use the exact same reloading recipe and get the same performance, just seat the bullets the slightest bit deeper.

Having said that, I also shoot 9.3 x 57, and in M96 actions, you get about 125 fps difference with the same bullet and powder between the x 57 and x 62, if you load to about the same pressure. You can seat your 9.3 x 57 quite long (they usually have very long throats), and even the "lowly" 9.3 x 57 can get you 3200+ ft/lbs with 270 and 286 grain bullets out of an M96 action all day long, without any rechambering. You may find it's just not worth doing unless you are rechambering specifically for maximum power for some critical reason.

I agree with Northman999,
There is little to gain in rechambering the X57 in X62 except for someone who wants to use avaialable ammo.

The M/98 will take the standard lenght (83.60mm / 3.29") but there is a concern with the M/94 based rifles, as magazine lenght is only 3.240" for the standard (i.e. military and comercial other than 9.3X62) vs 3.260" for the M/649 (on the same action).
Rechambered ones at Trade Ex have the magazine altered so it feed 3.29" OAL ammo.

One or the other I suppose. I do want the extra velocity of the x62. Are solid copper projectiles available in .366? That's where is see the advantage of x57.

Still undecided. I narrowed down my big game choices to 9.3x62/x57 and .338 Win Mag...

Well, I would like 8mm Rem Mag being a 8mm enthusiast, but cost, availability, and will have to stick with solid copper to get the most out of it without shredding the jacket. Excellent caliber but not economical in any sense. And I don't like Rem 700 actions. Traditional Mauser all the way :)

Just bought a 146 from TradeEx. After inspection and if all is well, I plan on getting it reamed out for x62. I want the ammo availability and extra velocity at range for moose and elk hunting.

A 246 would be choice... but I joined the HVA bandwagon too late.

So, what (quality) gunsmith has a 9.3x62 reamer?
 
Beavermeat,
There are only 5 246 in N-A... as per they only made 227 of them... and only two are in original form.
If it's one plan to rechambered a 146 to X62, buying one already done from TEC usually saves quite a bit of $$$ (when they have them).

That's right, I remember you mentioning this before. I looked at all the 146s that TEC had in stock and I settled on this one. It looked good in the pics he sent, hopefully there is no rust and pitting under the stock.

I wanted a rifle that was not personalized. I have seen some "gunschmidt" work on some HVA rifles, and I hate fixing other peoples mistakes. This way I get the scope mounted the way I want, and the bolt handle modified the way I want. And I like that stock :)
 
I've a really nice unit from Tradex that fit and finish wise holds it's own quite well, actually. Spend the extra 100$ and it will surprise you what Tradex has.
3200 fps... Yikes, I dislike the recoil on mine with solids at 2400 fps.
3200...you see stars after firing?
 
Actually, with a rechambered 146, you end up quite with a 246 alike... the "real" thing having a "N" and three digit serial.
The one you choose seems in pretty good shape.

Got it today, not too bad for a gun made in 1940 and the bore, throat, and crown look excellent. Stock needs some work but it's still solid.

Dumb question. Will 8x57 no-go gauges work with a 9.3x57? The case is the same, and the gauges don't measure the shoulder.

:agree: The 9.3x57 can do the job easily enough for N.A. critters within reasonable range. Makes for a nice
lead boolit launcher.:)

Update:Just bought a Husky 96 9.3x57 & brass from Tradeex. :dancingbanana:Now all I need are dies and a decent boolit mould.:runaway: Couldn't fookin' help myself.;)

Yes, it works! :)

I was wondering about seating the bullets way out in the X57 to gain more case capacity. My question is, how do you know how much you can up your powder charge from it, and how do you measure what kind of pressure you are running at?
