RCBS is now labeling their dies as ".32 S&W Long, .32 H&R, .327 Federal". Off the top of my head, I believe the exact product number is 21412 (I have a ridiculous memory for completely useless numbers, especially if there's a pattern). No other major companies have labeled their dies specifically for the .327, yet (that I am aware of).
.32 H&R dies are what everyone is using to load the .327 Federal.
I've read a few, scattered reports of Redding .32 H&R dies not being suitable for the .327. I'm sure they're from production runs prior to the .327's release, but don't know (not enough details).
SHUCKS.....a 32ACP or 32S&WLONG FL sizing die will also FL size 327 brass for goodness sakes.
Not all .32 S&W Long dies have enough internal clearance to accept the length of a .327 Federal case. Most .327 shooters are successfully using Lee and RCBS dies, from what I have gathered. (I use RCBS dies.)
HOWEVER... .32 Auto dies are not appropriate for sizing .327 cases. There is a small difference in cartridge dimensions. Using .32 Auto or .32 S&W dies to size .327 cases will over-work the brass, and cause premature failure. It'll work, temporarily; but it will cost you more in the long run.
And, of course, you still have the issue of internal clearance. .32 Auto and .32 S&W sizing dies are not designed to accept cases even as long as .32 S&W Long. So, .327 brass is a no-go.
