So I got a message saying “Hey, check this out!” or something similar. It is a brand of ammo I’ve never heard of before…( 2 of them). So I look. Darned if it isn’t actually a new idea.
Note the flutes on the bullet. They are shaped to deflect material hydraulically into side channels. Supposedly gives the effect of a hollow point while not limiting penetration. Very interesting idea, and kind of novel.
Underwood Ammunition is a family owned business started by Kevin Underwood in Charleston, WV. A lifelong shooting enthusiast, Kevin began reloading in his spare time. Quickly, a small reloading press turned into an entire loading operation including presses and stations set up for over 40 calibers. With a rapidly growing business Underwood Ammo relocated and built a brand new facility in Sparta, IL so that we might better serve our customers.
$28.99 for a box of 9mm at this time. Didn’t find a cartridge count, but weight is about 1/2 pound, so about 20? as a guess? Saw one write-up on another site where they did a velocity test and they tested as “as advertised or faster” (some makers products are, er, not quite as fast as advertised…)
Does something similar. Guess I’ve not been watching bullet development for a while… I found it interesting that they have applied their solid copper tech to some older lower power cartridges as a kind of ‘upgrade’. Since I’m fond of older and smaller as it makes for nice compact guns… the .32 ACP interests me. Well, that, and the Walther PPK was James Bond’s gun ;-)
There are many excellent older cartridges with performance constrained by the metallurgy available for the firearms at the time they were designed. Some are so good, as in the 45-70 Government, they have been updated for modern pressures and re-released as modern cartridges, others, like the 32 ACP will probably remain with low operating pressures, due to the number of guns in existence.
Is there a way to bring modern performance to the low pressure cartridges through advanced projectile design and manufacturing? At Lehigh, the world’s most innovative projectile and ammunition manufacturer, the answer is a bold YES.
We are pleased to announce the release of our Xtreme Cavitator family with the first cartridge being the venerable 32 ACP.
The Xtreme Cavitator uses a unique geometry to form a vapor pressure spike at the nose blanketing the flank of the bullet with a long envelope of air as it passes through media eliminating side drag and allowing deep penetration. The heck you say? No, it isn’t voodoo or marketing hype, it is physics. If you are bored, look up super cavitation torpedoes; the dang Russians where there first. The fact is, all bullets create cavitation; we just created a design with a unique nose and an air reservoir groove to accentuate the effect. How does 13.5” of penetration from a 32 ACP in 10% gel sound?
We were not satisfied with a deep penetrating solid, but then applied the science of our XP and XD technologies to use the nose to redirect the hydraulic energy radially, creating a larger permanent wound cavity than any expanding solid. We merged this concave surface into a square nose that defeats barriers by dividing the hoop strength of the contact media.
The end result is a conservation of energy from a square nose to breech entry barriers, to a concave surface directing hydraulic energy outward creating an enormous wound cavity, to a cavitation point that blankets the bullet with a boundary of air reducing flank drag and allowing deep penetration.
That is one mean looking bullet…
They put up gel photos for penetration and channel shape and include feed tests / reports:
Cartridge: 32 Auto
Bullet weight (gr): 50
FTM – Fluid Transfer Monolithic
Box qty: 20
Velocity (fps): 925
OAL (in): .945
Penetration (in): 13.5

Note: Feeding Capabilities
The list below will outline which 32 Auto’s we tested the XC’s in and which Guns we have been notified by our customers that there have been feeding concerns:
Tested / Verified
Berretta 32 Tomcat
Walther PP Manurhn 7.62
Barrier Performance Chart per FBI Protocol
Nice, that! Finally an ammo maker who tests their product in several real guns (not just a test stand) and takes reports of any feed issues experienced. And gives you more than just wt/velocity info…
