In Dakota's magazine they have a hunt with the "423 Dakota." On their web page they have a 404 Dakota that shoots a .423 bullet, but no "423 Dakota" listed.

Are they the same thing that they just put two different names on? Or, are they actually going to roll two seperate .423 caliber cartridges?

Thanks
Dennis

I believe the .423 Dakota is based on a shortened .338 Lapua Magnum case necked to .423".

And the .404 Dakota is based on the .404 Jeffery case.

The .404 Dakota brass has equal rim and base measurements, and length is 2.5 inches I think. (a kinda "fat" 30-06 piece of brass)

You can find the specs and prices for the brass at the site: www.dakotaarms.com

But they do not have the .423 Dakota-Lapua up yet, except for two completed rifles for sale in their inventory, one of which is at the Shot Show.

We should expect more news after the official unveiling at the 2006 Shot Show.

Gossip is that the .423 D-L is 2.490" in brass length and has a 35 degree shoulder.

Note that the .404 Dakota is 2.580" in brass length and is said to be the idea of a Dakota customer who wanted to neck up the .375 Dakota to .423 caliber. Dakota did it for him and ran with the idea.

If the pic below comes through, it shows the .416 Dakota with 2.850 brass length.





We'll have to wait for the full specs on the .423 Dakota-Lapua.

Good prices on brass from Dakota.

If you buy 100 pieces, it is only $1.40/piece up to and including the .404 Dakota.

.416 and .450 Dakota is $1.80/piece.

They also sell .338 Lapua Magnum brass by Lapua for only $1.40/piece.

I've got the dies and brass for the .404 Dakota, a 10" twist stainless McGowen barrel to be cut to 23" and put on a stainless Ruger MKIIM77. Just windowing the box of a 7mmRM ought to do the trick.

Dakota stuff is good stuff. I just can't tolerate all that fancy walnut and "wood upgrades." In the words of Patrick Henry: "Give me synthetic liberty or give me death."

Anyway, Dakota Arms is the inspiration for Hilltop Arms, but I was wildcatting the .338 Lapua Magnum before they were.

I just can't believe they would shorten that case to 2.490", give it a 35 degree shoulder, and call it the .423 Dakota-Lapua. Surely this is just gossip. Tell me it isn't so.

I like the .427 Lapua Kifaru. It is no less a mouthful than the .423 Dakota-Lapua, and sure fills a magnum action better.

450 Lakota Thunderstick (.458 cal)(short nose and short neck!)
307 Lapua Chui (.308 cal)(long nose)
337 Lapua Simba (.338 cal)(long nose)
377 Lapua Nyati (.375 cal)(long nose)
427 Lapua Kifaru (.423 cal)(long nose)
457 Lapua Tembo (.458 cal)(long nose)
470 Mbogo (.475 cal)(short nose)
510 Tatanka (.510 cal)(short nose)

All the caliber designations ending in "7" are unadulterated .338 Lapua Magnum case body and shoulder angle with caliber-length necks, chambered with long throating to allow 3.800" COL with long monometal bullets.

Now there is a unique caliber designator number for each of the eight cartridges from Hilltop Arms. This will make references simpler:

450/307/337/377/427/457/470/510

Why would anyone take a case as large as the Lapua case and then shorten it? If you are going to build a new magnum then build a magnum! If you want a lighter load you can down load it. Rip, what have you been able to get in FPS from the necked up Lapuas that you have done?

2500 fps with .458/500gr in the .457LT: this will be reduced to 2400 fps in a 22" barrel for practical lethality.

2700 fps with .375/300gr in the .377LN: this may be upped to 2800 fps easily, but no more is needed.

The point is to keep pressures reasonable, in best quality brass that is slick feeding from a Magnum action, with a reasonable length barrel, of 22" to 26", whatever the preference. It is not to get highest velocities possible, just some nicely lethal velocities.

I expect 2500 fps with .423/400gr in the .427LK, and 2600 fps with 380 grainers, and 2800 fps with 340 grainers, and 2900 fps with 320 grainers: This is AFRICAN SHEEP RIFLE NO. 2.

The .337LS is a long throated .338 Lapua Magnum (CIP).

The .307LC is a long throated .300 Lapua Magnum (CIP).

The .470 Mbogo will do 2500 fps with 500 grainers, though it could do 2700 fps if desired.

The .510 Tatanka will do 2500 fps with 570 grainers, no more needed.

The .450 LT will do 2250 fps with 500 grainers in a 22" barrel, featherweight rifle.

That's my story and I'm sticking to it.

The 7-338 is interesting. Buy a wildcat bullet from richard graves, 200grain with a bc of +- 1.0 I think.

Shot it at 3300fps, and it should be sheep rifle nr 1..

This is a quote: The big 200 gr ULD really spoils you as far as limited wind drift. At a full 1000 yards, its only 1.0 mil hold for a 10 mph 90 degree crosswind.

Ooh-la-la! That's the idea. Do you mean he has a .338/200gr (for my .337) or a .308/200gr (for my .307) with such a fantastic BC?

I have some Barnes TSX .308/200gr flat base bullets right now to try.

If Mr. Graves has an ULD with BC greater than 1.0 then the .307 Lapua Chui will beat the pants off the .50BMG's slow moving heavy projectiles for target work.

I wonder if a 10" twist will work?

Fantastic idea. I will need to look into that. Any contact info or must I Google in hopes of finding something, eh, Nortman?

PS: Only .423 caliber rifles may serve as African Sheep Rifles.

The .307 Lapua Chui would indeed be a fine World-Wide Sheep Rifle, however. HA!/DOA might have to change the name of that one to the ".307 Lapua Snow Leopard."

the 458-404 dakota looks neeto!

.284 200grains..

This is a unfinished webpage from Richard Graves :
http://www.wildcatbullets.homestead.com/index.html

The BC of all these bullets are not published.. but they beat almost anything out there..

You want a 350 grain .338 cal, he has it, with a nice big BC. Or how about a 100 and 107 grain .224 bullet.

Send fiftydriver a PM.. he is the one making them.

Aaah.. I thought the smallest was a 7mm caliber..

but I see its a .308.

Nortman,
I see. I figured we were on different frequencies there, and something was too good to be true. .308 is as small as I go with serious Thundersticks. I suppose we will have to look to GSC for the high BC .308 and .338 projectiles for target work.
