I've been looking for a set of 280 Rem Ackley Improved dies and while there are some sets avaible I was wondering if its possible to use a chamber reamer to ream the dies as well as the chamber? Anyone had any experience with this sort of work? All feedback/information will be welcome. :)

I'm sure it could be done. But in a sense you would be ruining dies. And you would have to find something the exact same size to ream the die.

Not possible to ream a finished .270 die as they are harder then woodpecker lips.
PTG makes unheat-treated die body blanks that can be reamed, then hardened afterward.
The other thing is, a die reamed with a chamber reamer would be too big to size cases for that chamber.
The die must be reamed slightly smaller to allow for brass spring-back after sizing.
Custom builders would either ream the chamber, then sharpen the reamer under chamber dimension just enough to ream the die with it.
Or have a set of two chamber & die reamers.
Clymer, Manson, and others make them.

Was actually thinking of reaming .280 Rem dies rather than .270 Win dies. But your post does awnser my question. Was thinking that if I where to ream my .280 Rem barrel to .280 AI, that I could use the reamer to ream the dies, but as you explained I need a differnt reamer to provide the brass room to spring back, Thanks, you've been a huge help! :D So my next question would be; Do reamer suppliers have differnt reamers for dies and chambers?

You did say .280 didn't you!! :D
But the caliber doesn't matter, you can't ream finished dies, for the reasons listed.

Thanks, makes sense, now that you've pointed out that the dies are hardened. :)

"...the dies are hardened."
Try running a file over a sizer, see what that does; a reamer would do the same thing.

Several die companies used to make a custom die for you if you sent a few fired cases with your order. I think Clymer still does it and perhaps Redding and RCBS still do.
