Lehigh Defense Xtreme Hunter 10mm Load Data

[Zaydok Allen]

Hey all,

Tomorrow I will be picking up my 10mm Auto carbine. It's a Kriss Vector CRB with a 16" barrel. I'm excited.

I have been looking at different load data available, and have watched a number of Youtube ballistic tests on various 10mm bullets out of carbine length barrels, and I'm noting something not unsurprising. Common expanding 10mm bullets aren't really built to stay together when pushed to 1300-1750 feet/second, depending on bullet weight. Petals sheer off, jackets separate, and while the terminal effectiveness may still be there, I am thinking more an more that a solid projectile makes sense.

I have no illusions about what a 10mm carbine is meant for, but I am interested in developing some loads I could use to put a deer down effectively out to say 150 yards.

I'm curious if anyone has loaded the 150 grain Lehigh Xtreme Defender bullet for 10mm, and if so, what load data did you use? I looked at Lehigh's load data and they don't have anything listed for that bullet weight. As it is a solid copper bullet I'm not comfortable improvising.

If you have used this bullet to hunt with, was the wound channel acceptable in your mind? I don't really believe gel tests are that representative of what a bullet will do to an animal, and I don't want to load something expensive that is no more effective than a hard cast lead bullet.

Underwood loads this bullet, but I can do it way cheaper.

And here is the bullet I'm referring to.

Please share your thoughts. Am I on a fool's errand?

Here is the load data for Lehigh’s 140gr. pill. Maybe a bit of help from the reload brain trust here @ THR will chime in.
We previously encountered a similar question when Lehigh introduced the 65gr Xtreme Defense for 380 Auto & we were searching for 9mm load data. Lehigh usually offers load data sheets a few weeks after product introduction. Check back on their site from time-to-time.

Nosler has a data sheet for their 150gr JHP here: https://load-data.nosler.com/load-data/10mm-auto/

Good Luck AoG

Slight deviation from OP (pistol)... I have chrono'd my 180 gn 10mm loads at up to 1290 fps from my G20. Longshot powder.
I use almost exclusively Longshot as it burns very clean at pressure and throws them downrange faster than anything
else I've found. Also tremendous in 9mm, 38spl +p, and .40. I personally only shoot/load pistol.
Higher velocity on the solid pill that is that Lehigh bullet should not be an issue at the velocity you are seeking.

Thanks. I was wondering about using that Nossler load data for the 150's andvstarting low. Not sure I want to do that though. I've been checking back on Lehigh's website for a few months, waiting for load data. No luck. Maybe I'll email them.

Yes, I have a pound of Longshot and 4 lbs of Accurate #9 I plan to load 10mm stuff.

Warm loads to be sure.

And yes, a solid monolithic bullet should work well at high velocity. Any possible deformation would have very minimal impact.

Good.

As a basis for comparing different projectiles in a homogeneous medium, ballistic gel is fine. But unless the target you are going to engage is an amorphous blob of processed cow hooves, there is no mechanism for extrapolating a bullet's performacne in ballistic gel to its performance inside a living creature. In my opinion when it comes to predicting the terminal performance of a particular bullet in an animal, gel tests should generally be regarded as worthless, at best, and misleading, at worst.

I’m using the Lehigh bullets in .357 Sig. Has anyone had any practical experience with the Lehigh Xtreme Defense or Xtreme Penetrator bullets in any caliber aside from testing in ballistic gel?

Yep. Differences in tissue density and the presence of bone sort of negate the test's applicability to real life terminal ballistics in a living creature.

I wish we would change over to calling it a "damage channel" or a "disruption channel" rather than a wound channel when testing bullets in gel. Wound channel implies it is comparable to what would happen in a living target when it really isn't.

Marketing.

None the less, I understand the need for a standardized test. The irony is people are NOT standard in distances gel blocks are shot at. But that's YouTube for you.

There are reviews posted here and there, mostly from hog hunters. I never see any pictures though.
