So I have a solid man crush on Underwood Ammo now since I got my .460Rowland up and running for the 2019 Hogpocalypse .  I just ordered 65 gr. .357 Sig and 65gr. +P 9mm Lehigh Extreme penetrators.   Solid copper.  Anybody use?

I’m also curious about these.   While there penetration is impressive, all the talk about wound cavity sounds too good to be true.   Is this a better mouse trap or just  marketing.

Wasn't "Extreme Penetrator" your nick name in College?

Doc has commented here and else where about this design... Comparing them to other fluted designs like the Devel projectiles from the 1980s


If I may provide one example of a past quote from the Doc...

"This idea of a solid projectile with flat point and flutes has been around for a long time. We tested a .45 Auto 185 gr +P solid w/flat point and flutes for NSW back in the late 1980's or so.

Despite media and vendor hype to the contrary, these solid fluted bullets just punch a hole in tissue like any FMJ--there is no mystical hydraulic energy, magical pressure spikes, absurdly enlarged wound cavity, etc...

Nonetheless, this design can be a good projectile and offer decent terminal performance. "

I never bought into the hype, but curiosity has on occasion had me wondering how they do after passing thru barriers.  I would guess penetration would be good.

Yo homey, is that my briefcase...?
