Almost 26" of penetration... 
Based on all the other 10mm balistic testing you've done; how would you compare the wound track or permanent cavity of this projectile to others (gold dot, barnes, nosler, xtp, etc, etc)?

The cavity left in the clay was scary.

Looked a lot like other 10mm and .357 mag bullets that didn't expand. Maybe a little more cutting but nothing really impressive. Went pretty deep to be sure, but a heavier FMJ or hard cast would probably go a lot deeper. I'm pretty sure the ONLY thing this would do better than other loads is penetrate soft armor or hard barriers.

Also, remember that the clay is not a ballistic media on its own. Its only purpose is to provide a yielding backer to the vest so that if the bullet is stopped, it can show you a snapshot of how far the back face of the armor deformed. When bullets pass through clay, it moves out of the way and stays there, whereas gelatin and tissue stretch and return to shape. Gelatin will show cracks where it stretched too far but tissue can stretch much farther without damage.

Appreciate the extra insight.  Based on a review of several of your tests, it's hard to tell how the permanent cavity compared (diameter and cavitation length) to other projectiles. 

You were quit clear about superior performance against soft armor/barrier. 

However as a hunting projectile in 10mm;  do you like these more, less or the same as a 200 or 220 grain (large meplat) hard-cast?
Bottom line in YOUR opinion:  Worth the extra money vs. conventional hard-cast for hunting?

Thanks again.

Just my opinion but for really large game you'd want the 200 or 220 grain hardcast. These would be better for deer or hogs.

I think I'd prefer the heavier bullet for hunting or large animal defense unless a flat trajectory was a priority.

The crush cavity is generally about as wide as the actual projectile.

Raggedyman,

Have you done enough testing with WFN hard cast bullets to tell whether there is actually much of a difference in its wound channel than the wound channel of a typical flat nose fmj 10mm range load? Given that both bullets hold together, do you think that a WFN is that much better than a fmj?

Going through meat and bone? The big Meplat of the Hardcast will do more damage. This video might help you too:
