At the range yesterday doing ballistic gel shooting with a few loads in two different chamberings, one of which was .327 Federal Magnum. The test gun was this Taurus 327 TORO with a Gideon Judge optic.
As a control round, I used a .32 H&R Magnum Hornady 80gr FTX Critical Defense. The Critical Defense did not expand through 4LD, and I didn't expect that ti would. It came to rest backwards in the gel block, 13" in.
The .327 Federal Hydra-Shok 85gr projectile, normally an iffy expander in 4LD, proved that even an iffy projectile can expand if you put enough ass behind it. It mushroomed nicely and came to rest, also base-first, at the 14" mark, just beyond the Hornady bullet.
The 100gr .327 Fed Gold Dot worked exactly as predicted: It expanded like a catalog photo and was found tangled in the denim on the far side of the 16" gel block. This is pretty much identical to what you get from 9mm 124gr +P GDHP and HST, which are pretty much the current gold standards, and it's what the load was designed to emulate.
That's the load I'm going to sight the dot in with.
