Lehigh Defense: Xtreme Penetrator Ammunition

[GJM]

Make sure to test some penetrator ammo through a new M, as one in 9mm was my planned bear gun next summer.

lol! No "M" guns here. I just know people who are close to the inner circle.

I will be shooting these through the G40:

Underwood Extreme Penetrator 140gr
Federal Trophy bonded JSP 180gr
Corbon RNPN 200gr
Buffalo Bore HCFN 220gr
Hornady Critical Duty 175gr
Double Tap Hard Cast 230gr
Buffalo Bore FMJ 200gr

For the loads I haven't run through the chronograph yet, I'll do 10 each of them.

Any bets on which rounds will make it through the steel? My money is on the Underwood EP - but that's because I saw the video of it zipping through bullet proof glass.

Well it appears 3/8" AR500 steel is too much to ask of these rounds. I tried 4 of them and they barely made a dent. I tried the Buffalo Bore Hard Cast Flat Nose 220gr, Corbon RNPN (FMJ) 200gr, Federal Trophy Bonded JSP, and Underwood Extreme Penetrator 140gr. I was able to recover the Underwood and it is not a flat piece of copper. Next to it in the photo is the base of the Federal JSP. Any other test media y'all want to see used? I'm thinking 1/8" steel will do better.

* On the first shot with the DT, the slide didn't close. Tapped the mag and it went into battery and didn't have any more issues. Still using the OEM RSA.

Thanks for this. Does it look like the Lehigh penetrator held together the best of these loads?

You're quite welcome. I couldn't find the other rounds (or the rest of the Fed JSP). The EP round is pretty impressive looking though. You can still see the cross shape. Wish I had a scale to weigh it. I plan to get some clay blocks to put behind the 1/8" steel next time. Hoping that and some water jugs as backup will recover the rounds.

What I like about the Lehigh is that it has a very FMJ style bullet profile, which I believe makes it feed well in semi-auto pistols, and being made of a monolithic material, it seems likely to hold together, when hitting tough mediums.

Do you think the Lehigh/Underwood offerings are good options when complying with state/local FMJ requirements?

I wouldn't use these on the street. Too much penetration. What caliber are you talking? In 9mm if I had to use FMJ I'd go with a flat nose 147gr.

9mm. Thanks. Back to square one, FMJ = 45 ACP.
