you can do it, but it's really a chore when done right. You'd be better off with virgin 35 Whelen brass. You'll need to expand the necks out to pretty much a strait wall case and then start necking it down in steps (probably at least one anneal when you get the necks back down to around an 8mm I.D.). When you get the necks down to 7mm you may want to anneal one more time. I would set the headspace about .010" too long, and the very carefully bring the shoulder down to where the headspace is correct. After that you'll have to fire form the brass and then trim it to the correct length. I can only think of one case design that would be harder at the moment, and that's a 30 Meyer made out of a .284 case. The 35 degree shoulder is a killer!

Why do you need to do all this? A 270 neck is longer but the case is the same length to the shoulder and has the same headspace length and shoulder angle as the 06. There isn't going to be any length to trim because the formed case is going to be short. The neck might be a little thick but depending on the chamber it could be ok too.

"...could i just let it threw a 270 win Die set??? "

Certainly, it's a straight forward process. Lube the lower part well and push it in, pull it out, trim the length if it's needed (probably won't) and you're done.

It would be helpful for case life to anneal the new necks but if you anneal improperly and over heat them (to a visible red glow) they will be too soft and lose all bullet grip. Do a web search on 'case annealing' for lots of tips.

actually I was wrong, as I was simply crunching numbers in the top of my head. You cannot make a 270 case out of a 30-06 case. The 270 is about .046" longer than the 30-06 case. Also there is a difference in the headspace numbers even if they used the same case length. On the otherhand you could use a .280 Remington case to get it done. (2.540" verses 2.494")
