6.5x284 info

cntryboy1289 · January 24, 2005, 07:11 PM

Anyone know where I can find a 6.5x284 barrel for a model seven? I have found several from David Tubb, but I am not sure about his rifle. He called it a Texas 5 or something. Trying to save as many steps as possible on a new rebarrel project.

Barrel Makers:

Shilen
E.R Shaw
Lothar Walther
Adams&Bennett
Hart Barrels
Broughton
Bullberry
Badger
Krieger
Douglas

I'm sure there are more, but this is a start. I don't have their websites or addresses but you should be able to get them on a web search.

Are there pictures of this cartridge, or was that a typo?

Gewehr98 · January 29, 2005, 03:12 PM

It runs neck-and-neck with the older 6.5-06, and is a favorite for long range (1000) yard target shooting. The USMC was even playing with it for a while. The beauty of the 6.5x284 is that it fits in a Remington short action, compared to the 6.5-06.

Norma, Lapua, and Hornady offer factory brass for the round.

Chuck Hawks does a good synopsis of the round:

His load data is a bit light, because I've run 140gr bullets right at 3000fps from a 6.5-284. Load data closer to what I've used:

And the picture of the round:

I thought it would fit the model 7 without much trouble.

Gewehr98 · January 29, 2005, 04:48 PM

But just barely, and you need to watch your COL, especially with the heavier boat-tail 6.5mm bullets. If the rounds are too long, you run the risk of having a single-shot rifle that will extract and eject only fired brass.

6.5x284 is NOT a wildcat cartridge !!!

It has been formally made a cartridge by Norma and Norma and Lapua make the brass. Some suggest that the longer receiver be used so it isn't necessary to set the longer bullets so far back into the case.

Third_Rail · January 29, 2005, 08:22 PM

Ah, okay. It's not "6.5x284". It's "6.5mm-.284"

World of difference, the first one says the cartridge is 28.4 cm long!

Gewehr98 · January 29, 2005, 10:09 PM

6.5x284, 6.5-284, 6.5mm-284, 6.5mm-284 Winchester, and so forth.

It's still essentially a wildcat, until one of the mainstream rifle manufacturers puts them on the shelf. A-Square sells 6.5-06 ammo. Guess what, it's still a wildcat. A popular wildcat, but still a wildcat.

You can always get a custom chambering from the custom rifle folks, like Kenny Jarrett and Cooper, but they're far from mainstream. Personally, I doubt Remington, Winchester or Savage would go wrong with offering a rifle or two in the chambering. The Model 700 and Model 7 seem to be a natural for the round. The only problem is that both Winchester and Remington seem pre-occupied with their respective versions of the silly short magnum fad.

cntryboy1289 · January 31, 2005, 02:08 PM

Most of the 1000yd BR folks I know either have it already or are getting one. It is definitely a wildcat caliber for now seeing as it isn't being carried by all of the manufacturers. I have a cousin who has the model 7 rem and he wants it rebarreled to the 6.5x.284. It is a .260 right now. I would put it in a model 700 myself, but I think it will work with the model 7, keeping in mind what you said about the OAL of the round.

Dave R · January 31, 2005, 04:39 PM

So how does this differ from .243 Win, which is essentially a .308 necked to 6.5mm?

Gewehr98 · January 31, 2005, 05:29 PM

6mm = 0.243"

6.5mm = 0.264"

A .308 Winchester necked down to 6mm/.243" is indeed a .243 Winchester

A .308 Winchester necked down to 6.5mm/.264" is called the .260 Remington.

A .284 Winchester round has a 0.500" case diameter, with a .472" diameter rebated rim. The case length is 2.170" That's considerably longer than the 2.045" of the .308 Winchester case, and also wider than the latter's 0.470" case.

Can you see where these numbers add up? The .308 Winchester, being shorter and narrower than the .284 Winchester, has approximately 56 grains case capacity. Compare that to the .284 Winchester's fatter and longer case, which holds approximately 66 grains of H2O, nearly the same as the .30-06 Springfield. This means more powder capacity, for more velocity, in a cartridge that will still function in a Remington Model 700 short action, or even a Remington Model 7.

That's why the 6.5-284 Winchester wildcat is so popular.

Dave R · February 1, 2005, 07:06 PM

Gewehr, thanks for straightening me out. I shoulda knowed that...

Yeah, I'm somewhat familiar with the .284Win. I shoot a wildcat derived from that cartridge--the 7.5 Swiss!

That's right. In case you didn't know it, you can use .284Win brass in your K-31, or other 7.5 Swiss rifle. Once through the resizing die, then trim.

And yes, I can see why the 6.5/.284 would be so popular. Sounds like a .270 Improved in a short case.

Gewehr98 · February 1, 2005, 10:53 PM

If I didn't already have a good supply of Norma brass, I'd be resizing .284 brass to feed my M1911 Schmidt-Rubin, too.

Dave R · February 1, 2005, 11:16 PM

Gotta love those Swiss rifles.

cntryboy1289 · February 3, 2005, 01:17 AM

I guess I got lucky with my 1911, it has been rebarreled to .308
