I was wondering if anyone out there is/use to shoot this round. I have a action and barrel ready to go and was researching cartridges and ran across this one and it is bascially exactly what I want. I was originally thinking a 6.5-06 30 degree... but this is basically the same. I don't want a 40 degree AI ether.

I know about the 6.5-284, the 6.5-06 and all the other 6.5's, so I don't need info on them.

I was also wondering If anyone knows if you can get say a 280 neck die and put in a .264 collet for neck sizing? I have not used any of the collet dies so I'm not quite up to par on them. I have a vickerman seater so I'm not worried there.

Any info would be great.

In Donnelly's "Cartridge Conversion" book, he has a 6.5/280 RCBS Improved with a 33.99 degree shoulder angle (pg 784, 2002 ed). The case prep notes say:

280 Rem case. F/L size Rem. case in "Improved" die. Trim, chamfer and fireform.

Got the rifle all put together. I ended up using a .264 WM die to neck down and it chambers in my rifle perfectly using this die ran up till the shell holder touches the bottom of the die. I have only fired one round down the chamber, but it turned out great.

Cases from left ot right are .270 win, 6.5-06 standard, 6.5-280 30 degree. I can form the 6.5-280 brass from both .280 and .270 brass.

Nice looking case.It will be interesting to see how this performs against the 264 mag.I think quite possibly very close.

Thanks, I might send the rifle off for blueing here pretty soon, but I plan on getting some data asap. I'll report back when I get all the numbers. I am also curious to see what it will do. I don't plan on loading it too hot, but I'll do some testing.

Mate all you need is the Hornady neck size die, this die does not make any contact on the case body just the neck. I've been using these neck size dies for all my Improved cases 220 Swift AI, 243 AI, 270 AI and 30/30 AI.
That round should be wicked.

Good Luck

thanks for the info. I just ran across some of those yesterday, but they did not have a .264" die at the store I was at. I also have been using the .264 WM FL sizer and it has been working great for neck sizing and decapping. I have fired several rounds in one case, so now I'm on to looking for a FL die to bump my shoulder back.

I run a 6.5-300 win mag.All i use for resizing is a 264 mag die.I can bump my shoulder back with it.Why do you need to move your shoulder?

With 15+ firings on one case, they are a little tight to chamber without bumping the shoulder back, and or partial FL sizing.

Now a 6.5-300 WIn. Mag. should be a hoot!. I bet it's a barrel burner too. Of course it's not a whole lot hotter than a ..264 Win. Mag. Of course that's a known barrel burner too. Give me a garden variety 6.5-06. The barrel will last much longer and it won't be a whole lot slower.

It will take me a long time to burn the throat out at the rate I am using it.If it does start seriously loosing accuracy I will make a WWH 6.5 weatherby mag out of it.
