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.

It’s JC, the inventor of the patent.
I made only a prototype mold for 9mm and that was shown at ShotShow 2018. After that, Winchester abandoned the project.
The “S1” was the original patent filled for both companies (Quantum, before Polycase and Olin) but later there was a conflict of interests to determine exactly what belong exactly to each company. That explains why later were filled two separate patents, one for the tip itself and other for the bullet using this tip, each filled by the companies separately.
I can tell that Olin only provided the outer profile, including the ojive, the seat and the tail and I made the rest: the ARX flutes, the connection channels and the ribs on the tail to improve the attach of the tip to the lead core.
I guess that Olin abandoned the project because the terminal effects were not as espectacular as expected and this conflict of patents could increase the cost that Olin should have to pay for each bullet. I still keep the molds at home.
