Does some one have experience with this round.
If you build it on along action so you could seat the bullet way out and still feed it from a standerd 3.600 action.
With the larger case vol and high BC bullets would it make it a good shooter?

Thanks

No experience, but I have looked at it. I have a couple of .264WM, and would suggest the 6.5 RM is a much more sensible cartridge size. It is about 68 grains vs 81 for the .264WM. But it lost the battle in the bigger is better, and is an almost forgotten cartridge. Remington still seems to make brass for it, and you can get reloading dies. With a long barrel and good loads I suspect you can duplicate or beat velocities of the .264WM. I can't even get 3000 fps with 140 grain bullets out of the one gun I have that has a 22 inch barrel. These cartridges need lots of barrel to work.

It has almost the same case size as the 6.5x284 which comes in about 66 grains. Performance would be comparable. The 6.4x284 is becoming more popular, and the 6.5 RM is virtually forgotten. Lapua makes brass for the 6.5x284, and competition dies are there. Savage chambers some nice target guns in 6.5x284. It would be hard to overlook the 6.5x284 in a head to head comparison with the 6.5 RM.
 
6.5 Rem Mag is ballistically the same as the 6.5-06 AI. Which is a good thing to be, and puts it slightly ahead of the 6.5-284 in real world guns (as opposed to bench guns that are generally used at higher pressures them most sporters). You can build it on either a short or long action, and by an odd coincidence it works quite well through an x57 length action. - dan
 
Lost the race with Winchester, too bad as most if not all 6.5 bullets have great success for accuracy and longer ranges that outperforms its own size!If I was to build a Magnum gun in 6.5 I would consider this cartridge over the Winchester round, as I like screw ball calibres, and it is easier on barrels, than the winnie from all the guys I have talked who use the 264WM CARTRIDGE!

You rarely run into a rifle chambered in this anymore, seen a old 600 series about 10 years ago, thats about it!Dale Z
 
So as I have a Savage LA with a .531 bolt face do I

A build a 6.5 RM with no change to the mag, but have to find odd brass or make brass out of 7mm cases.

B build a 6.5x06 or 6.5x284 but have to find a .473 bolt face, and have to rework the mag for the smaller round.

I did find on other forums some people that have played with the 6.5 RM and are getting up to 3200fps with 140 vld witch seem fast.

I need help, what should I do..

Thanks
 
I'd go with the 6.5 Rem Mag. Brass won't be an issue and are still made by Remington. Any distributor can order you some if they don't have any in stock. Less drama then forming brass. IMO
 
Zywina,

Wasn't the .264 Win Mag built with SS barrels because of severe throat erosion being so over bore with original factory ballistics. Winchesters first belted magnum as well. Father of the .300,.338 and the .458 Winchester Magnums, if I recall. I always drooled over that caliber but went Rem mag and .270 instead.
.264 when I was a kid was the epitome of the long range sheep gun.


Wasn't the 6.5 used mainly in those short carbines, like the .350?

Brass is available but not that easy to find as Remington only runs it once a year.If I was building on a long action I'd go 6.5-06 or .264 Win Mag,depending on the bolt face you have.Because my donor is a 700ss 7SAUM I'm going 6.5 Rem Mag,the bolt face is right and it should feed with no problems.I am going to add a Wyatt box mag just to give myself a bit more COAL.I did manage to pick up 300 pieces of new brass:D Mur

I have a bunch of this brass, all once fired I believe, PM me if you wish to know more about it. FS

6.5 SAUM would be cool and easy too. Nothing wrong with the 7 SAUM either (got one of those as well) but I can understand, I'm a 6.5 slut as well!

I already have a 7 SAUM 700ss,so I had to find another for a donor,no way I was going to change it over.Finally got one from Omineca Sports,Thanks Tod!:D Mur
 
Nothing wrong with the 6.5 RM. As was already said, a belted 6.5-06'ish. Think ballistically superior 270. That's pretty much it.

If you have a long action Savage with a magnum face, I would just go build a 7RM and enjoy all the new wonderful super high BC slugs available. Easy to tune, no need to push things, a very accurate rds.

If you really want the 6.5 RM, go for it. May not feed as smoothly due to reduced length but it will work.

6.5 win mag would also be great and no feeding issues. Just tone down the loads to 6RM levels and you have the best of both worlds.

But the 7RM offers more yummy goodness.

6.5 Remington Magnum

My uncle came across a piece of brass from a 6.5 Rem Mag and he has kind of snowballed with it.

It looks like it would be a great round to produce some decent velocities in the 6.5mm range.

He ended up getting a few boxes of ammo at a gun show and is looking at doing a build off of a Rem 700 Short Action with a Shilen Barrel. Probably a 26" #3 (magnum contour) for longer range hunting and target.

Looking at the reloading manuals it should be very easy to break the 3000fps mark with a 140gr VLD, possibly even 3200 with a heavy load.

He is looking at picking up a reamer for it.

Anyone had any experience with this round? It is a shorter round but with a magnum base.

Here is a photo to see some comparison.

I have a couple of 6.5x55 improved rifles. one I use for f class it has a 30 in barrel and I run 140 VLDs and JLKs at 3000 fps. I have the other one in hunting rifle with a 20" barrel and I run 130 VLDs and 125 nosler partition at 3000 fps. The thing that most f class shooters find is that even if you can run 6.5 140 grain bullets faster than 3000 most of the time they don't shoot that well over 3000. I found that even when I was running 120 gr stuff in my 20" barrel. I could get them up to over 3100 but they didn't shoot well and I ended up dropping them back to 3000 fps. I am not saying this will be true for all 6.5s but they do tend to run best at around 2650-2750 or 2900-3000 fps. Some people have taken them up to 3400 fps and say the shoot well there but that is just way too hot for most guns. So there could be little point in building a rifle to push a 140 6.5 bullet to 3200 fps if it does not shoot well.
Now as I have said this could very from one rifle to another but as most f class 6.5s run similar barrel length they and found that 6.5-284 , 260, 6.5x 55 or even 6.5-06 all top out at about 3000 fps.
These f class guns need to shoot at around 1/2 minute or better, so maybe with a hunting rifle you would be happy with a 1 or1.5 minute gun and sacrifice some accuracy for speed.
This is not a hard and fast rule just something I found and it held true even with my shorter 20" barrel hunting rifle.
 
Well it's been four years since I started this thread so I finally got time to build a rig that I had parts for.
Just a up date because I dislike in finished threads.

So it started with a Steveins 200, add a 1 in 8 Shilln barrel chambed in 264WM, add a Timmy trigger, some type of Boyd's stock.
I piller bedded it and topped it with a Vortex Viper 4x16x50LR. Shoots ok for the first loads.
