Hello Folks

Had a couple of bolts apart to compare, though others might like to see how a Kurz compares with a Standard 98 bolt.



And now look away if you don't want to see a bubba'd Single square bridge Oberndorf Mauser Kurz Model B in 250 Savage (with a boltless Kurz round Model B also in 250).



Any thoughts as to how I should proceed on making the squarebridge into a "nice" using hunting rifle ?



I also have these bits:

Can you show more detailed pics of the top of the receiver, both rings, with the modern bases removed? IIWY I'd be exploring the possibility of using those extra bits to re-convert back somewhere closer to the original configuration. Can you show the top views of both rifles and their receiver rings? This type of project is of great interest to me!
Regards, Joe

What are you hoping to do with that Boltless one?

Well I'm pretty certain I have a genuine bolt located (and if not I definetly have a 'smith to make one), if I can get a genuine bolt I think it will stay as is . . a classic from yesteryear, although I would probably add the cocking piece sight to it. If its a replacement bolt then it might get a makeover.

Joe - I'll take some pictures tonight. I'm thinking like you, as long as I don't use a scope with an objective bell why not go back to the claw mounts (I believe this is the main reason why this style of claw mounts are not popular today, you just can't tip off a bigger scope . . . . opinions??)

I read on another forum recently where Rigby(if i recall correctly) was going to offer Kurz actioned rifles in November 2010 and would be selling replacement bolts. Actions made on original Mauser specs.

I did contact Rigby, and they never replied. Later I spoke to another London Gunmaker (to the Principle no less) and he avowed that ALL English gunmakers were sourcing actions from Reimer Johansen, who I believe obtain them from Prectl - same old loop.

The existing set-up

Front is a dovetailed claw mount base with a 6mm gap between two 5 mm legs (see base in pic above):



Aft we have a single 10mmx10mm square socket:



Not one nicely placed hole, they'd all strip at an instant, not that it'd matter that much because bubba didn't align them properly anyway

Sad.

I personally would first attempt to remove the Bubba inserts from both rings and restore the claw mounts as far as possible. The photos seem to show that the original holes and slots have survived largely intact and unaltered, so in my mind it would seem at least possible to restore the mounting system to at least a semblance of its original state.

From that point it should be possible to fabricate rings to fit the bases, I've done this several times and it's fairly straightforward work but also tedious.

Another alternative would be to consult the Recknagel catalog to find new replacement rings and their matching front base. Pricey and difficult to choose the proper size from halfway round the world, but it IS an alternative.

A good craftsman can fill in those off-center holes so they're unnoticable, not a big deal at all, and you'd then have the basis for a very attractive rifle. A little welding work on the bolt handle and you're in business!

The cocking piece peep is a nice thing to have too. Is the bolt modified somehow for it? Does the disc with the two holes scew to the rear of the bolt?

The rear of the cocking piece has a dovetail cut across it for the sight base to fit to. In my case I had a sleave made with a lower of set so the sight in its retracted position would be low enough to work under a scope in qd rings.

I have a similar Kurz action not a single square bridge, that has a dovetailed front receiver ring with a similar plug. It has been drilled and tapped for weaver one piece base. Other than that there is nothing else wrong. The action is too nice to scrap and the original bolt handle has a dish in it to allow for low scope mounting. I will have some custom bases made for it and it converted to single trigger and then I will get it stocked in the Rigby style in 250-3000!!!

Foster, FWIW I've used scopes having alightly-enlarged objective bells with Mauser & Mannlicher-Schoenauer claw mounts on several rifles. Scopes in the sizes like 4x or the small variables up to 2x-7x will work well, or at least they've worked well for me in the past with custom bench-made rings made to fit the original claw bases. FYI FWIW.

I have an unusual set of claw mounts. Unusual due to the fact that they work in reverse of traditional claw mounts. the claws are mounted to the rear and the lock is front. Large objective lense are no hindrance at all. i don't know why all are not so made!

Where did you source that cocking piece mounted sight?

Hello Lawndart

The rifle came as a package with the cocking piece sight included (the sight was probably the best part of the whole deal, and one of the main reasons I went with it - I don't think the vendor reralised how hard they are to get).

Do yo know who the maker was, I've seen pictures of a couple on the net but no-one seems to know who made them or whose the design is?

Its not for sale just now, but once I get my "kurz" projects sorted out inn a month or so I may well offer it if you are interested.

Cheers - Foster

Very good quality and a nice guy to deal with.
