Ever seen an Mauser in 9,3x62 Magnum
      #388665 - 06/01/25 03:45 AM

Just received some ammo boxes in 9,3x62 (Mauser).

Old RWS, one marked with "Magnum". If i go into old ballistic charts there is no big difference between 9,3x62 and 9,3x62 Magnum.

So i am wondering if there are rifles chambered in 9,3x62 marked with "Magnum" ( like the 8x60 Magnum)?

In around 1923 to 25, according to John Taylor, the ballistics of the 9.3x62 were raised to 2,340fps from 2,175fps with both soft and solid 286gr.
Could it be that box marked Magnum was an early box of that ammo?

Yes, I had a TypeB 9.3X62 stamped "MAGNUM" on the barrel just as some of the 8X60s are.

first time I see the 9,3x62 Magnum label.
imho, a marketing gag in the 1930s like 8x60 Magnum, must have been a thing then. today every second cartridge is magnum, also ice cream is called magnum so the word is a little bit outworn.
this way most Brennecke cartridges would deserve the Magnum title, the 9,3x64 in any case.

I prefer Magnum Bombe, this is german as possible

could be this moniker was used only by RWS or have you see it also with DWM ammo?

Here's the rifle I had.
The "MAGNUM" was a bit messy like it was double struck but surely an original Oberndorf mark.



Same as marks on 8X60 MAGNUM rifles.



I believe that the "magnum" name was simply because this version was a higher velocity as Daryl mentions. The bullets seem to be spire points as well and my rifle had a layer of rubber in the front of the magazine to protect the soft point bullets in the magazine. I had seen this only in one other Oberndorf '98 and believe it to be original from Mauser.

According to Taylor, the original loads of 2,175fps with both soft and solid 286gr. killed just fine and did not need the update to 2,340fps.
What is most interesting about these ballistics, is my Model 46 Husqvarna in 9.3x57 made 2,170fps with resized 300gr.RN's and 2,200 quite easily with 286gr. & 2,300fps with the way too soft 270gr. Speer SRN.

imho, it was a marketing gag only. the loads are all in the CIP maximum and there is not such a thing like a +P load in europe. the cartridges were load to the maximum they had and this was called "Magnum" then.

CIP max working pressure was 57,000PSI (pezio) for 7x57, 8x57, 9.3x62.
The 6.5x55 was 55,000 psi.
The 9.3x57 had no CIP max working pressure(does now, apparently), however Norma loaded it to 34,000CUP(copper crusher), however the same rifles were chambered in the same guns as 6.5x55, 8x57 and 9.3x62 - some M74 Husqvarna's even barreled/chambered in .30/06 which has a CIP pezo max of 59,000psi.

No, a CIP maximum pressure existed from 1940 on only. Until 1939 the gunmaker could specify the factory load his gun was to be proofed for.
The 1934 handbook listed these loads and pressures.
9.3x62:
18.5 g = 285 gr rn, 710 m/s = 2329 fps, 2900 at pressure
16.7 g = 258 gr H-jacket, 820 m/s = 2690 fps, 3250 at
And a 9.3x62 “Magnum” load:
16.5 g = 255 gr boat tail copper pointed, 823 m/s = 2700 fps, 3350 at. That was a 16 % pressure increase over the original 285 gr load.

Axel would mean the "Schiesstechnisches Handbuch für Jäger und Schützen" by RWS. I have the second 1940 Edition but the first edition could be made in 1934.

"No, a CIP maximum pressure existed from 1940 on only. Until 1939 the gunmaker could specify the factory load his gun was to be proofed for. "

yes I know, this was simplified to make it easy and short. this so called "magnum" loads are close enough to today maximum load that I see no real difference. if they realy exceed today CIP maximum? hard to know because pressure proof today with original and very old ammo would not been trustworthy. old catalog data is to be taken with a bucket of salt. nobody had a chrony then to measure what realy happen in his rifle with a 60 cm long barrel. today you find ammo from time to time, CIP proofed, still a little bit over maximum and it got the proof mark. yes it happen and it don't make rifles explode, its allmost ever mistakes or careless handloads when the rife is in good shape. so, if the "Magnum" load was realy over reasonable pressure they could not sell it on an open market and I believe a reputable firm like RWS or DWM would have never sold a cartridge you can load in any rifle where it would not been safe under any circumstances.
thats what I mean, sorry for don't speak clear.

That 255gr. load at 2,700fps very closely matches the .358 Norma Mag. factory load(250gr. 2,756fps). No flies on that load and it utilizes the case's actual capacity.

Both of my "factory" 9.3x62's & the Styer owned by the grizzly hunter from Hungary we had back in 2010 or so, measured .454" on the shoulder of a fired case, not .451" as noted above. I have 2 of his RWS (I think) factory cases he fired in camp to check sighting of his scope before he went hunting with his assigned guide.
I measured the case capacities and they match mine, at 78gr. water.
