Commercial Oberndorf 98 in 6,5x55 - info needed



There were very few Original Oberndorf commercial 98 Mausers .

At least 2 specimen here documented.

There were a lot more modified standard actions by riflesmiths.

If you try to load more than 4 rounds in a 98 standard magazine box without modification you are in trouble.

So what I want to know are the exact dimensions of the factory made magazine box for the Commercial Model 98 to hold the usual 5 rounds ( A modified standard box ore did they use a special made box following the exact dimensions of the older Model 96 ?

If you compare the Magazine Box Dimensions of the Mod 96 Swede ( in brackets )and a standard 98 Mauser

Length : 84 mm ( 82,45 )

Height : 33 mm ( 33 mm)

Rear width : 22,4 mm ( 23,09 )

Front width : 17,7 mm ( 18,3 )

Anyone here with a Original Oberndorf 98 in that Swede caliber ?

There is a factory memo in one of Speed’s books that gives factory mag box length and width dimensions. I don’t recall if it gives depth. I can try to dig it out later tonight, or perhaps someone can beat me to it. However, I’ve notices that rounds with wider shoulders and bases have the inside of their mag box walls scalloped. That is the case with my Oberndorf 9.3x62, anyway. It’s a standard depth mag and holds 5 down.

The Originals were not scalloped. Scalloping was used as aftermarket modification by some smiths.
The dimension table in Speed´s book lacks the dimesions for the 6,5x55.

It makes no sense to me that Mauser would put out commercial sporting rifles that would not feed well enough that they needed aftermarket modification. I’ve come across several Oberndorf sporters with the inner magazine wall scallops, including 10.75x68. I’m not saying you are necessarily wrong, just that I don’t see why Mauser would put out poor feeding rifles that needed help.

Could someone tell me what in this case meaning when talking "scalloping". I took my 6,5x55 Mauser down once and doesn´t notice anything special in it´s magazine.

That is a good question.
Can´t imagine that CM1 had in mind the bread and butter treatment as shown in the picture.
That feature shows every Oberndorf magazine box - small or big cartridge.
If so ,it was a misunderstanding.

What some smiths did were longitudinal radiussed cuts on the sidewall to give more space. Never a factory treatment.

A very nice & certainly a most interesting piece to say there Justcurious!
I've never heard of 'scalloping' before...I have now!
One to hand down thru the family, definitely a keeper this one.

I am talking about the “bread and butter treatment”, but the scallops are different for each round. The feed rails can be a little different as well. I can’t imagine that the follower for a 6.5x55 would be any different than standard, (if there really is a standard) but who knows.

What an enormous expenditure only for the magazine boxes.

There were at least 18 (caliber related ) differently dimensioned boxes .
Every box either with floorplate leaver release or button in the trigger guard bow.
And moreover every type with DST or single stage.
Because they simply did not insert an DST into the otherwise identical bottom metal , but made it integral with the bottom metal you must quadruple the 18 caliber related dimensions and we have round about 72 maschine setups for the bottom metal alone.

That is only one aspect why the Commercial 98 Mauser rifles are so reliable and highly estimated up to now.

Re: Commercial Oberndorf 98 in 6,5x55 - info needed

I was just reading John Speeds Oberndorf Sporter book, and he mentioned that the floor plate on 9.3x62 Mauser actions are thicker, I assume, to allow a little more recess room for the follower spring. I wonder if the same is true for Oberndorf 98 sporters in 6.5x55. I own an original Type A in 9.3x62 with an inside bow floorplate release. The magazine is definitely standard depth, but I’ve never examined the floorplate. It holds five down, no problem. I have a complete Oberndorf commercial 30-06 action. I can take some measurements of the two floorplates for comparison, if you are interested. BTW: the 9.3 x62 floorplates don’t really look thicker to my eye. The 10.75x68, which Speed states are also thicker, look quite obviously thicker, to my eye. I would love to find an original Oberndorf 10.75x68 bottom metal.

Speed shows two factory lists of magazine dimensions. Neither of them mentions the 6.5X55. However, there is a simple way of determining if the magazine is original to the rifle. If it is, it will have the rifle's serial number stamped on the rear of the magazine.

Matt

You are correct on all fronts.
No rifles would have left the factory requiring " aftermarket" modifications in order for it to fit or function correctly. To suggest otherwise in my opinion is incorrect.
Each and every cartridge had the necessary factory modifications to the magazine box and followers to get correct function.
I dont have experience with the 6.5x55 , it may well be that this chambering sacrificed capacity and was not necessarily published.

No doubt Smiths who thought they knew better did fiddle with modifications.

My B type 9.3 is the same as yours Matt...and definatley a factory initiative.

I have 2 (maybe 3) original Mausers model B's in 6,5x55. Give a few days and I will try & measure one.

Hi justcurious

Do you have any information on caliber rarity for the Mauser Type M? I just passed on one in 9x57 at the recent Borg auction and there is another in that caliber in the upcoming classic arms auction in S. Africa. I had thought the 9x57 might be rare but the appearance of these two so close together is making me wonder. I also used to think the .30-06 might be rare but I've seen a few of those as well.

thanks in advance for any information.

@ Kebco
Thank you very much.


The 9x57 was very common on the continent .(Stutzen and rifle)

The Stutzen in 30-06 was more a rarity , the rifle in 30-06 also quite common (at least in the US )
