Need help sizing 327 Fed Magnum Case

[Crash_Corrigan]

I finally got around to try to load some virgin Starline cases in 327 Fed. The sizing die stops squeezing down the casing just before the rim.
After the case is loaded it will not fit into the case gauge. It goes in just to the bulging part where the full length sizing die failed to reach.

What can I do to get it to fully size the casing?

What brand of dies? Are they for the 327 Mag or just 32 S&W, 32 H&R Mag etc? Did you buy them new? If not,, has someone modified them? Are you adjusting them properly?
Have you chamber check them in the gun,, not just the gauge?

Isn't there another thread about this already? Could have a sworn there were a bunch of replies in that thread.
