Re-chambering 9.3x57 to x62

I have been reading that x57 plenty powerful enough and many re-loaders (key word) love it. I got stocks of 8x57 brass... But I don't reload yet. Re-shaping brass is something I will try down the road after some years of reloading practice. At the start I will be doing the basics.

For now I want the x62 because of the commercial ammo availability so I can get the rifle into the field for next years hunting season.

And I'm really liking this HVA 146. It fits me like a glove and points very well. I might have to get an other. :)
 
I've read on this forum where Why Not and some others have stated that the 9.3x62 is in performance essentially a .375 with 5 in the magazine. So if the x62 is roughly equal to the .375, and the 9.3x57 is roughly equal to the 9.3x62, does that mean that 9.3x57=.375 H&H?
 
All the following stems from sitting in an airport at 4am and having too much time with a smartphone, so forgive me and feel free to factcheck. I also realise your point is in jest, and also fair, but the rabbit hole is tempting.

.30-06 will push a 250gr to 2,300fps too, and meets x57 performance. Every step down in performance a fellow needs to justify as not affecting his hunting. We both know the .375 H&H has a lot more on tap than the x62, on paper, with published loads over 2,700fps for 300gr (Barnes, 300gr solid, RL15, believe H4895 does it as well). There is a roughly 700ft-lb difference between too x57 and top x62 loads, and double that spread at roughly 1,400ft-lbs between top x62 and top H&H loads.

In the end, they'll all kill the same things. It is my barely informed opinion the .375 H&H is a good idea if leaving the continent, and the x62 a reasonable second of highly similar performance. What I'm hoping will be my new favourite .375, the Flanged Mag, is a dead ringer for x62 performance so I can't critisizing the x62. In North America, there isn't enough trajectory difference with the bullets available in 9.3 to highlight a big difference between the x57 and x62, and both are sufficiently potent I believe for our continent. Go to .375 and you've added meaningful power and almost more importantly far better bullets and selection, with your 250gr TTSXs, 300gr boat tails, and the like, to make meaningful differences at longer North American ranges. So I have an easier time calling x57 and x62 similar in effect than x62 and .375 H&H- I am however open to challenges on this. Properly academic here now!

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?

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?

He said foot/Lbs (energy) not fps (feet per second). Let's not get confused!
 
Personally I wouldn't rechamber it, the 9.3x57 is easy to reload and in a 98 action is only 100-150 fps behind the 62. If you are going to rechamber, have a recoil pad added at the same time, those Husqvarnas will get your attention if you chase speed.
 
Also, what about the sights? In my 146 velocity has to be a little over 2000 fps for it to regulate to the sights "as is". Faster rapidly gets a higher point of impact (14 to 20 inches).
 
FWIW, the 46/46A and 146 were zeroed (regulated) to hit a 20 cm - in the center - circular target @ 120 meters, using a 6 o'clock hold, with a 285 grains bullet @ 2067 fps. Also, no rifles left the factory unless it shot a 5 shot group not bigger than 7 cm.

Interestingly... that's why I just bought a second one :O

What is the effect of shortening the barrel on a x57 or x62?
 
I agree, there is very little loss. I see less than 50 fps difference from my 600mm (23.62") barrels vs those in 560 mm (22")
 
I scooped a Husqvarna M96 actioned sporter from Tradeex in 9.3x57 and have brass and dies in the mail as well. Once I get the rifle and slug the bore, I'll get a mold made for a 285 gr. bomb from Accurate Molds. I intend to to load the big pill to around 1500 fps. for game within 100 yds. Think "Big Cooey.":)

Nice looking rifles.

Well, this ain't a "sporter", it's a model 46 and seems to be a nice one too. It's also actually based on a in the white Carl Gustav M/94 action.

The rifle pictured above is a Husqvarna 46 fer sure, but what would not make it a "sporter". Looks pretty fookin' sporty to me. The Husqvarna M96 Sporter I bought from Tradeex is just like this one, but in better shape & I wouldn't be surprised if the rifle is marked Model 46a.
No matter, I'm gonna be tossing a shyte load of lead from my new sporter project. A Timney or Huber trigger will no doubt be in order for this wee thumper.:)

Well, a "sporter" usually refers to a remodelled military rifle or in Europe, a Target / Varmint rifle.
Trade Ex named them that way because that's how they were entered in the Canadian register.... and no, they were not marked with the model designation. If it's a 6.5X55, then it's a 46B (rarest than the 46A) and if it's in 9.3X57, it's a 46A. But there are also rifles in the early 640 serial # range using this same stock.

That's pretty consistent with my experience velocity wise.

You wouldn't happen to know how the 6.5 cal versions are sighted? I'm assuming something like the older 155 or 160 grain load. Thanks for any info.
 
Ship it to Epps. Not a big deal. Wrap it up, ship it off and wait.

They did mine and it works fantastic.

I know we discussed this via pm when you were first looking into doing this and if I remember correctly, you really didn't want to ship it but I think that's your easiest option.
