Custer wore the 1st "Arrow shirt".
Given the size & power of “Ivan”, we must now … and ever be Vigilant.
I still have some of the 9MM Fed.
If I remember correctly, it was a more consistently expanding bullet at the time. Most other jacketed 9MM HP bullets were iffy expanders.
And it offered reasonable penetration when expanded.
I don't remember for sure though.
IIRC, the SWC/HP bullet was also loaded in .357 Magnum. I think I got a box (from Gil Hebard?) and shot it up.
Always wondered why this stuff faded away.
It just wasn't any better, and sometimes was quite a bit worse, than 158-grain +P plain lead hollow points from Remington in performance. In fact, that round really wasn't surpassed performance wise in .38 Special until the last 15 years or so, when bonded hollowpoints and monolithic copper HPs came into existence. I still have several hundred rounds of Remington LHP +P from my first decade of carrying revolvers.
Federal even brought the Nyclad back sometime around 2009 (iirc) and then discontinued it about a year later.
