Making your own brass

Yes.. you can make 280 out of 30-06. You neck may be a touch short. you neck may need a bit of inside trimming.. But 280 Rem was from 30-06 in the first place.

Yes, you can form 'short-necked' .280 Rem from .30-06. And, yes it will work just fine.

But it didn't come from .30-06.
.270 Winchester and .280 Remington are based on the longer neck and case length of .30-06's parent case, the .30-03. (And, technically, even .30-03 is a 'child' of the equally short-lived .30-01 -- identical to .30-03, except for a thicker rim.)

In today's market, the only readily-available sources for .30-03/.30-01 length brass are (or at least longer than '06): .270 Win, .280 Rem, .35 Whelen, and .35 Whelen basic.

Yes, Hornady is good enough brass but there could be more weight variations than with others. Norma brass would probably not be considered by most to be worth twice the cost of Winchesters. Between Winchesters and Remingtons, you may find Remingtons to be more desirable since universally Remingtons are heavier with thicker necks than Winchesters. Not putting down Winchesters, for mag cartridges I use more Winchesters than anything else, with Remingtons coming up a close second.
 
It's pricey as hell but Nosler .280 brass is some of the very best I've seen. I know, I just bought 100 pieces. No prep necessary.

Yes, Nosler is good brass, heavy with thick case necks, the way brass should be. Expensive but I get it when available (especially, of course, when nothing else is available).
 
I have used a lot of 30-'06 cases in my 270 Winchester with zero problems. So yes, it can be done. The best plan is to just get correct 280 cases at any price. In a world of shortages and having to make do with what you have, then go ahead. It would be a little easier to use 30-'06 cases, but 270 cases will be more nearly correct. You will need to expand 270 necks to 30 caliber, then resize in your 280 die. I would suggest loading a long bullet until it is touching the rifling somewhat firmly and use a starting load as the pressure tends to be higher when the cartridge is loaded to touch the rifling. This way, the the cartridge will be held back firmly against the bolt face as it is essentially headspacing with the bullet against the rifling. After that, just load as normal 280 cases.
Heck, just order some proper 280 cases.
 
No you can NOT use .270 cases for .280. Look at your reloading manuals or cartridge dimension books fellas. The problem starts with the rim diameter of the .270 which is .532". The .280 rim diameter is ..473" which is the same as 30-06.

We're talking about .270 Winchester.
You're looking at .270 Weatherby or .270 WSM. (Neither of which actually has a .532" rim diameter in any drawing that I have, but both are close.)

Those .270s are different beasts, entirely.
.270 Weatherby is based on .300 H&H.
.270 WSM is based on .300 WSM (which is, itself, based on a modified .404 Jeffery).
