Bauska BBK-02 Large Magnum Rifle Action
      #73566 - 10/03/07 07:25 PM


Forum members,
Just recently purchased this rifle action and am planning on building a large magnum caliber rifle with it. Still looking for additional information on this particular action. Here is some general background information that I have gathered so far on the make and model of action plus the company that produced it.

The action is a Bauska BBK-02 Large Magnum action also known as the Olympic Arms Ultra Mag BBK-01. Information on the internet has been very limited. Here is what I received so far from other forum members on other firearms forums.

Quote: These receivers were very probably the finest bargain in the world of custom rifles. They were a little rough but with some efforts, a Classic Mauser Safari style rifle could be produced. End Quote

This is an excerpt from a press release:

It is with some regret that I received word from Olympic Arms President Robert C. Schuetz that the magnum bolt actions marketed from Olympic Arms as the BBK or Ultramag Action will no longer be produced.

Olympic Arms purchased the tooling to produce these actions from a Montana resident named Jack Bauska back in the late 1980's. The actions are large frame Mauser style actions for Safari size cartridges like the 375 H&H and larger. With a box magazine length of 3.85" and a collar size to match, these actions were some of the strongest bolt action receivers ever made (investment cast), and could handle anything up to and including the .505 Gibbs cartridge.

Last manufactured in 2002 (?) with an upgraded 3 position Winchester style safety and Timney triggers, the Ultramag actions, still often referred to as the Bauska, or BBK action by many, were highly sought after actions for custom rifle manufacturers around the world. Standing orders existed for the Gibbs Rifle Company as well as the smashingly famous Holland & Holland Rifle Company.

Troubles with production existed from the get-go on the production of these actions. As the tooling was Korean made, and parts were less than 100% interchangeable between actions, there was some dislike for the Ultramags, but when properly finished and assembled, made a rifle, I dare say, second to none. Tooling wore out quickly once brought to the US for their last production run, and only a few hundred were actually totally manufactured in the USA by Olympic before the tooling just simply wore out and needed a major overhaul to continue production.

Well that major overhaul, turned into a complete replacement with new tooling top to bottom. This, considered next to the growing demand for AR15's in general (the Olympic Arms mainstay), and the continuing successes in gaining market share for Olympic Arms brand name in civilian, LE and governmental circles, the time and engineering needed to continue the Ultramag action continued to be pushed back, until today that is, when production was officially cancelled.

While Mr. Schuetz refused to say "Never again", he did say that the reappearance of the BBK was "highly unlikely", and "definitely not" in the foreseeable future.

Gut feeling: You'll never again see the BBK/Ultramag actions. If Oly ever puts out another bolt action, it will be on a billet action designed by company VP Brian Schuetz who has tabled this thought in the past.

For anyone interested in reading up on the BBK action the previous owner of my action provided this additional information and book reference: Made in Korea for Bauska Arms of Montana. Double square bridge, Model 70 type safety, etc. If you have access to Tom Turpin's book "Modern Custom Guns" from Kraus Press, see pages 42,43,44 for explanation and pictures and page 23 for 3 excellent examples of custom rifles built on this action.

Just finishing up a 505 on a BBK. This has been a collaboration with Frank Wells, a smith of some renown with several BBK rifles in his portfolio. The action I started with was set up for the standard H&H case requiring a bit of work to function with the 505, but, as you state, it is large enough in all dimensions to accomodate the 505. The action does not have a bolt anti bind feature but it's straight forward to install a M98 type bolt guide, which I did. Requires broaching a groove in the rear ring and milling the bolt for the guide. The magazine is JUST deep enough for 3 rounds of 505 so my rifle has a drop floor plate for added space much like the Westley Mausers from the 1950s. Looks clunkey unless you like clunkey...since W/R used it, I like clunkey. I think you have a good basis for a nice rifle.

Nukalpiaq,

SOme pictures of the gun building process, please.

Otto,

And some pictures of your 505 whenever you have time. Thanks in advance. Please also ask Frank to revive his website. It has been dead for two years - a sad thing as it was a magnificent one when he first put it up.

Good hunting, gentlemen!

I'll talk to Frank tomorrow and, with his concurrance, post his contact info. He has plans to visit AK this summer. Perhaps you could arrange a meeting.

About pix of my 505...I'm not smart enough to post them. I'd be happy to email a few to someone who has that expertise.

I owned one and sold it.

Well, first off it is definitely not a Mauser.

Next, "bargain" is a very misleading term. Yes, the purchase price is cheap-but not nearly as cheap (not "inexpensive") as the quality of the action. It can be turned into a decent action, but if you do not do it yourself and consider your labor free, then it will wind up costing more than a Granite Mountain Magnum Mauser.And even after you spend more than a granite action costs, it still will be lower quality than the GMA.

There is no need to start making them because they are just the CZ Magnum action. The only meaningful differences are the BBK bolt is larger than the CZ (.730" vs. .700") and the threads are British Imperial vs. SI. I have had people tell me I did not know what I was talking about here many times, and for that reason I took pics of the the BBK next to the CZ 550 Magnum from several different angles. The series of pics clearly show the actions on my bench are the same. Well not the same because the "rough" CZ is 1000 times better finished than the BBK. I looked just now but did not find the pics on my hard drive.

Yes, they were sought after before CZ started making their actions. That scenario has changed.

It all depends on what level of quality you need to make you happy. You can't build a top level rifle with one of these actions, but then most people want a lower quality product anyway. With a good bit of work

THey are gone and I say good riddance. THe only redeaming quality they had was the larger diameter bolt for rounds such as the .505 Gibbs and related wildcats. For anything other than a .505, use a CZ.

man, that reads a lot more negative than I meant it.

The ad copy that was quoted in the original post is, well, just normal advertising BS. You can make a decent rifle with this action, but it will always limit the total quality of the rifle. butthat is just fine for almost every one.

And as far as it being a sad state of affairs that the action is no longer made, it only impacts folks wanting to use the .505 case. For everyone else, it is no loss as the action is still being manufactured. And in higher numbers and to a higher quality level, I might add.

So build yourslef a nice rifle on the action and be sure to post some pics here when it is finished!

I appreciate the input, varied opinions based on actual experience is informative. The rifle that I am considering having built would be strictly utilitarian, "a hunter's rifle for a Hunter" you can say. Since I live here in Alaska and am planning on having the rifle built for moose, bear, bison and walrus hunting it needs to be able to handle Alaska's weather conditions (snow, rain, sleet, mist, etc.) and rough terrain.
To start with I would have the action worked on to improve function and reliability. I would then have a stainless steel barrel installed, contour: a # 4 if I went with a caliber in 375, a # 5 if I went with a 416, barrel length will be 22 inches. As for chambering I have always wanted a 416 Rigby but may go with the 375 Remington Ultra Mag.
Once the action, barrel and chamber work are completed I will have it KG (Kal-Gard) coated or coated with a similar weatherproof finish. I will also have the Timney trigger adjusted to a 3lb trigger pull. I will then have it send to McMillan Fiberglass Stocks for a complete stock installation job, in my favorite molded-in camouflage pattern. LOP will be 13.75", stock will be padded with a Decelerator recoil pad. This is my plan for the rifle so far, strictly utilitarian for hunting in Alaska.

The .404 Jeffery might be a more useful chambering for your rifle project. It hits harder than the .375, but without the recoil of the .416's. Should work well in that action.

Quinhagak, Alaska on the south bank of the Kanektok River, one of the very best flyfishing rivers in all of Alaska, but that is another story for a different forum.

BBK-02 Caliber Selection: 375 H&H or 400 H&H ? [Re: Nukalpiaq]
      #74466 - 24/03/07 01:07 PM


Reconsidering my caliber selection for this new rifle. The 375 H&H would be a good caliber for this action, ammo is readily available here in Alaska. Another caliber I have been considering and reading up on is the new 400 H&H, which is based on the 375 H&H case. This caliber could be a viable option as well. Has anyone heard about whether or not ammo is available yet or had experience using this caliber? The more I think about it, from the information I read on the internet the 400 H&H would be a great round for hunting brown bear here in Alaska. Any thoughts on this new caliber?

I would think a 375 H&H would be more verstile in Alaska.

Personally I agree totally with your approach for an Alaskan bolt but would use a different action like a granite arms action as others suggested above for a custom project.

Short of that and being tight with the dollar I would look at the new 375 Alaskan in 375 Ruger and replace the trigger with a Timmey trigger.That would give a versatile standard length action rifle that could be used,even abused somewhat, and still get the job done

Your BBK would be a bit large for any case based on the belted H&H...that's personal opinion, of course. Because of the magazine length...3.85" I think...you could have a long throated .375 H&H or a long throated 416 Remington, which would provide loading flexibility with long, heavy bullets and still let you shoot factory ammo if need be. Your action would not require any mods to accommodate these cartridges.

      #74805 - 28/03/07 09:18 AM


I have another question to pose, taking into consideration the size of the action: bolt size .730", magazine length 3.85", etc.
Considering these two identified qualities that make this a "larger" magnum action, what would be the most appropriate caliber to consider for this size of action, besides the ones I have listed below? (416 Rigby, 505 Gibbs) What would you build?

OTTO,
I am planning on having an anti-bind feature added to my BBK, never had this kind of gunsmithing done before sure would like to see a photo of the modification that was done on your action. It would give me a reference point to work from when I talk to a gunsmith. Would this be possible? Thankyou.

Anyone ever heard of the .458 Express, was wondering what the OAL is on this cartridge and what folks think of this cartidge as a candidate for the Bauska BBK action? Thanks in advance.

Nukalpiaq,

Prof Koos Badenhorst who designed the 458 Express has a website devoted to the round at: http://458express.com/

Hope you find this useful - you could e-mail him to ask for his advice.


Otto,

I would be happy to post pictures for you if you want me to. Please e-mail them to me.

Good hunting, gentlemen!
