Thread: Dakota calibres

What became of the various Dakota offerings? Especially the 7mm and 300 ? Don’t see or hear much of them these days with plenty of new entrants to the big 7 & big 30 cal offerings.
Assume there’s still a few rifles around? Brass ?
Does the slightly larger base/head ( 0.545 vs 0.532-535) still work with normal magnum bolt face?
Like many of the non-belted magnums around the design seems to harm back to the original 404 Jeffery case.
Might be an interesting case for wild cat development if it fits a standard magnum bolt face

I reload for a 300 Dakota

There’s three that I know of in NZ

Pretty sure there's more than three but I don't know how many more. Not heaps by any means as I assume Dakota cost was always a factor but a few examples reached NZ over the years.

A friend of mine has had one for many years here in Wanganui.

Do they fit a standard magnum bolt face?

If Dakota brass is based on 404 Jeffery dimensions they probably fit a Tikka magnum bolt face. What makes ms think so is I have a 300 Blaser and the case is suppisedly based on 404 Jeffery dimensions. The Blaser case fits an unmodified Tikka magnum bolt face. I used the Tikka magnum actio for my rifle.

Both 7mm & 30 Blaser Mag are 0.535. Dakota are 0.545

You are correct. I checked.
404 Jeffery is 0.543

I looked up the Blaser 300 Magnum to find that it has a 0.535 inch case head diameter. The 30R Blaser cartridge has a case head diameter of 0.531 inches (per Wikipedia diagram: 13.5mm, divide by 25.4 mm.in to get 0.531 inch).

The 404 Jeffrey has a case head diameter of 0.543 inch (Wikipedia), which is close to the 0.545 inch case head diameter of the main Dakota series cartridges (Terminal Ballistics).

I have a 330 Dakota. A .340 Weatherby case (with standard magnum case head diameter of 0.532 inch [Terminal Ballistics]) is retained loosely by the bolt-face/extractor claw of my 330 Dakota. I can't state that the overlap of the extractor claw is enough to provide reliable extraction of case made for the Dakota from standard magnum brass. It looks like it might.

So far as I can find, only Dakota cases or .404 Jeffrey cases have an appropriate Dakota rim diameter. I've just fallen into 240 once fired 300 Dakota cases, which I plan to expand up to 0.338, so with my current supply of 127 330 Dakota cases (mostly new brass) my case supply problem is solved.

I have seen a custom case maker offering new Dakota brass for $6 each. These would presumably have the advantage of being properly headstamped. Also, Redding sells a $200 die set made to convert .404 Jeffrey cases into the 330 Dakota (instructions included), probably available for all the Dakota line. Of course these days, the 404 Jeffrey cases are also rare and expensive, though not nearly so bad as the Dakota.

The Parkwest Co. which now provides Dakota rifles has no cases or ammo available. They aren't optimistic about getting any, as makers require a prohibitive number in an order to cover tooling up. Hendershots offers some Dakota ammo, but it will be made from 300 Dakota cases, and so headstamped.

The Dakota rifles are fine examples of craftsmanship and aesthetic, worth having, keeping. I think a good gunsmith can alter the bolt face/extractor claw to properly fit a standard magnum case head. If that is done, then Dakota cases might be made from 338 Rem Ultra Mag cases, or possibly 375 Ruger (not sure about the Ruger, the case body is slightly larger that the Dakota's).

Didn't they have some quirk like very short necks?

Hey nothing wrong with a short neck...

I thought that was more of an issue with wsm’s ?

There are a few 7mm Dakota around. I think the bolt face of most magnums need to be opened slightly up to accept the case.
The 28 nosler is pretty much the same but with a normal magnum head.

I went to visit the Dakota factory in Sturgis twice in the early 2000’s , as a friend of mine over there knew one of their foreman.
It changed hands I believe and has been renamed something else in the recent years.

Is brass available here ?

If you're looking, which calibre ? I may know of some but would have to check calibre / availability.
