So , Im at the range this afternoon with my new to me Husky sporter 98 in 9.3x57 that finally seemed to arrive seeing as I ordered it from camp last month in Alberta and asked Anthony at Tradex to ship it on the 20th before he left moose hunting. Ive got a bunch cast lead stuff in different flavours loaded up and after setting up the chrony, entering the header in my notebook and the conditons at the time finally the time has come to give her heck. I take careful aim at the 25 yard target take up the slack in the trigger let out half a breath and squeeze. Bang goes the rifle just like it should , everything seems good , pick up the bino's and gleefully note the nice round hole within 3/8" of the center of the bull. Looking good so far Im thinking to myself as I pull back the bolt handle and lift up the fired case checking the primer and case head area for expansion when something catches my eye and I discover that its not a 9.3x57 at all, hell no why with the tiny stub of a neck left on the case and the hugely blown out shoulder this puppy's a 62!!
Well now that I look back to this morning when I was cleaning the packing grease out of some of the recess' of this puppy I did note that someone sometime had really spent some time working the feed rails and the feed ramp , the bolt slides slickly and the timing seemed to be perfect with the loaded 57 case. Now Im wondering if it was oringinally a 62 or some gunsmith in Sweden ran a chambering reamer and didnt mark it. Last time I did something like this I managed to touch off a 270 win in a 300 win mag and ended up rupturing the case.
Just some food for thought
 
It is funny how peoplewho do not understand headspace will get so excited about 5 though of "headspace" when 5 mm of headspace is no problem.

I have seen a lot of 308 fired in a 30-06 without incident.

Excess headspace caused by a chamber too far forward is not a danger.

Excess headspace cause by a bolt too far back can be very dangerous.

perfect headspace in a rifle with a shallow chamnber is dangerous.

The issue is making sure the case is pushed far enough into the chamber to be supported.

Other than the wasted work on the 57 mm brass, the bigger case is a bonus, no? Are the bigger cases to be made from 30-06, or is the new chamber too fat?
 
Loaded round on the left 9x3x57 with 285 CGC ,The case in the middle is the fired x57 case, and the one on the right is a brand new graff 9.3x62 case

To answer your question, this will be my third 9.3x62 , Im happy it turned out this way but going to be looking for a 98 in a x57 too as I have the 9.3 sickness fairly bad, I currently have a 96 in x57 and its a lot of fun lobbing lead potatoes at the range. And no I wont be necking up 06 brass as x62 brass is readily available and good quality.

News flash, its a 1938 model 146 that started life as a 9.3x57 and was at some point rechambered to x62, A fellow on the Swedish sporting rifle board has kindly educated me , kinda ####ty they didnt mark it though!

Just curious BawanaDave, what is it marked as? I have a Husky 98 in 9.3x57 (also from Tradex). Mine is simply marked "Kal 9.3mm", nothing to specify that its x57 or otherwise. I thought that was a bit unusual, but just assumed that was how Husquvarna marked them all. My brass does come out looking pretty much how it went in though.
 
Mine is definitely x57, the bit about the brass looking the same coming out as it went in was supposed to be humorous. I checked out your gunboards link, good info there. I'm a member on that sight as well but I don't check in as often as I do here.
