What is there to know about this cartrige?

What actions may be used, what bullets, what brass, what everething, have you used it on DG? Would you use it on DG?

Comparisions with other DG calibers are very welcom.

the 460 G&A comes in two versions, a short and a full lenth...Built on an improved 404 case and is really quite a well designed case..It will work on any standard lenth action that can be converted to the 404 lenth which is shorter than the 375 H&H so any Mauser or M-70 will work...

I believe today however, with the advent of factory production and factory that I would simply opt for the 458 Lott as the ballistics are quite simular.

Man I like this forum. I go to make a cup of coffee and when I return I have an anser on my question!
Keep em coming.
I'm not opting to by a DG rifle, I'm just curious.

Johan,

The Dakota line of cartridges is based on the shortened .404 Jeffery cartridge, except the .450 which is based on a Rigby sized case. The designer felt that after expanding the .404 brass to accept a .458" bullet there would not be enough shoulder for positive headspace control in factory chambers and cartridges (due to the combined tolerances).

I know of many handloaders who have had .460 G&As built and who load for them with no problems.

A-Square sold the brass in cylindrical form if you bought enough of it, but decided not to load it as a factory proposition.

The Chay Zed people took a look at building a Jeff Cooper commemorative of his rifle "Baby" in .460 G&A, but decided not to do it.

Ray is right about the .458 Lott. It is now being offerred by at least two factory makers and two ammunition companies.

Get a copy of Jeff Cooper's book, "Fireworks", and read all about it!

AD

And also more recently "To Ride, Shoot Straight, and Speak the Truth".

Okay. Don't think I would by a book right now, but I will look for them if I get the chance. I would like to hear from people that have used it. I read about it in a G&A not long ago.

Johan,

If you use google.com and search for <460 g&a> you will find several of Jeff Cooper's writings on the Internet on this subject.

I have handled his rifle, and also shot John Gannaway's version of the same rifle. It was simple to hit a 10" gong at 100 yards off-hand using the ghost ring sight, and the recoil was very mild.

personally, I think the 460 G&A is only a slightl improvement over a 450 Ackley. I really suggest you look long and hard at the 470 MBOGO. This is a beltless .416 with the shoulder moved foreward. Its case capacity is equal to the 500 A2 without a belt, and in ,475 caliber. It is a great design and capable of 2500 fps with a 500 ge .475 bullet. This is a cartridge that will be hard to improve upon if hunting is your main purpose.- Rob

Hey Robgunbuilder !
What would a rifle in .470 Mbogo cost, i was thinking of that nice-looking one mounted on a sort of pintle,there was also some .50 BMG'S PICTURED there,,i hope you know what rifle i mean,,i'm not sure who pictured it(Mitch?).
What is this rifles real potential ?
Are brass easy to form, from .416 Rigby ?
When are somebody going to load for this one and have it posted on the reloading site ?!
On beforehand thank you !!
Per "577"

Hey hunterJim

I did a seach and found a lot of interesting stuff. Thanks.
Anyone used it on game?

Johan

Here is one site I found, mostly about CZ.
http://www.dvc.org.uk/~johnny/jeff/jeff5_4.html

Very interesting.

Johan,

Jeff Cooper has loaned that rifle to several friends going to hunt Cape buff and other game.

I also recall that on one hunt Jeff shot two buff with one bullet.

Per577- The 470 Mbogo is a great cartridge and I believe it's true potential lies somewhere between the 460WBY and the 500 A2. 470MBOGO's website details his experiments and reloading data. As far as cost is concerned, it's hard to say, I just turned down an offer for the one you described for $1500 US. This was built on a 1917 Enfield action that was extensively rebuilt and rediculously complicated IMHO. I think one could be built on a CZ550 for about $600 if you kept the CZ stock and just rebarreled and didn't want open sights. The cases are made from Mast Tech. basic 416 brass, but the longer shoulder requires you to have the reloading dies. These can be obtained from CH4D or RCBS. You just can't make one out of .416 Brass. An alternative is to go with the old .475 A&M which is the same cartridge but with a belt. You could use 460 WBY brass in this case, but you will still need custom dies.-Rob

308 , read on Gunsmithing trigger for a P17 post Bongo 500 made a Cambaco a very similar to the 460 G&A .

Daniel

Thanks Robgunbuilder !

I don't think that there are many smiths who wish to make a sporterized Enfield action anyway(p-17), cause it's like you said,,,soooo complicated !Well i think this cartridge will do 2700+ fps with the 500 gr. bullets,,but now i am planning to get a .620 IMPROVED , or a .727 IMPROVED !And i am also thinking of the .577 T-rex, if brass from HORNEBER still is available.
These are futureprojects,,,goal is as much power ican get my hands on !

308 Winchester, That article you read in G & A was in their 500th issue edition and was a reprint of the original some years ago. I asked the same question last year here and some of the guys mentioned the potential headspacing problem. I ended up going with the 450 Dakota with John Ricks on the CZ mag Mauser action. I'm new to big bores and everything I know, which is not much, I've learned here. Thanks to all you guys.
