I was questioned the other day about the various “screwdriver bit” projectiles, and remembered the patent for the Winchester Hybrid X. After a brief blitz of publicity from SHOT Show 2018, the Hybrid X quickly faded into obscurity.
As the name implied, it was an odd hybrid of a screwdriver-style polymer tip fitted to a jacketed, segmented core. Upon impact, fluid flowed past channels in the sides of the tip to separate it from the jacket and core. The core would then fragment into four pieces plus the jacket itself.
The first patent application for the tip was filed in December 2017, followed by one for the projectile itself in February 2018. If the tip looks like the PolyCase ARX Inceptor bullet, that shouldn’t be surprising as PolyCase’s Juan Carlos Marin and Paul Lemke were among the credited designers in the patent application.

I like to think I keep a good eye on the industry but I really don’t remember these…likely because I never cared for the screwdriver style projectiles.
I appreciate this series – lots of info I didn’t know.
