Please note - I’m not interested in a discussion of calibers for bear but rather in bullet performance regardless of caliber.

Not long ago, I had a couple of close encounters with black bears that started me thinking about my choice of bullets in my field carry load. I had been using Gold Dots in my .357 Sig. I was concerned that Gold Dot bullets might not give me the penetration I would need if I had to shoot a bear.

I did a bit of research and discovered the solid copper bullets made by Lehigh Defense. These bullets use what Lehigh calls fluid transfer technology. I was impressed by various ballistic gel testing videos of Lehigh’s Xtreme Penetrator and Xtreme Defense bullets. In gel, the Lehigh bullets penetrated deeper and disrupted more gel material along the way than any of the other bullets tested in comparison including Gold Dot and HST bullets.

Some folks argue that these gel tests do not duplicate animal tissue and are therefore unreliable. That’s possible but looking at the gel strictly as a test medium, the Lehigh bullets outperformed everything else in the same medium. That has to count for something.

Others, having tested these Lehigh bullets by shooting them into a hunk of butchered meat, argue that their results are nothing like the gel tests and are more consistent with shooting a hunk of meat with FMJ bullets. Their reasoning is that muscle is more elastic than ballistic gel.

Still others maintain that live tissue and organs exhibit more fluid characteristics than butchered meat and say therefore the gel tests are nonetheless somewhat valid.

So, I bought some of the Lehigh XP and XD bullets and loaded some test rounds. Accuracy is good but I’m curious about performance. I’m thinking that in worst case they should be at least as effective as a hard cast SWC on a large animal.

My question is, has anyone actually used these Lehigh bullets on a live animal? What were your thoughts?
 
I have never used copper pistol bullets to hunt game animals. Copper is lighter than lead so it takes much more of it to make weight. This equates to extra length with equates to less powder. I have shot them for target with rifles and found the extra length messed with my accuracy (meaning riflings that are optimized for a particular length bullet calibrated from the mass of lead don't like a longer length of a copper bullet as well). Short ranges were fine so in a pistol it would also be fine. I was shooting out to 200 yds with heavier bullets.
I went back to cup and core bullets for hunting after that.
Just be prepared to be using less powder to load these due to the extra length and taking somewhat of a hit on velocity.
And good luck finding load data. Maybe Lehigh can help you with that.
I won't use them anymore, this is just my opinion, maybe you can work up something that works for you that you can share with us.
 
I’ve already worked up some loads for these bullets. I didn’t have to sacrifice any velocity but I wasn’t able to use AA#9 powder, which is one of my preferred powders for the .357 Sig round, due to the bullet length. I found two faster powders work well for me in this application – Bullseye and Power Pistol.
 
Power Pistol I can believe, I don't use Bullseye. You may want to try BE-86, it's very agreeable with my .357 mag. I'm glad your velocity is intact. Let us know how you make out. I like my slow powders in my magnums so I just don't experiment with anything that won't let me use them. I actually have some all copper bullets in .357mag but I shoot mostly S&Ws and Ruger revolvers and they don't like long bullets so much because of their 18 3/4 riflings at longer distances. So most of them are still sitting on my shelf. I have no clue what riflings a .357 Sig has so I will stop here.
Good luck.
 
I have been meaning to try BE-86. I hear that a lot of guys like it. I’ll include some in my next powder order. The Alliant rep told me that BE-86 has a flash retardant. That might be a good thing.
 
In theory those should work, but these have proven they will work.

FWIW, Shoemaker is a regular poster on some other hunting related forums and he provided many other details not in the linked story. He has been guiding for bear in Alaska for over 30 years and knows what it takes to kill one. He had been testing this load prior to carrying it and was confident it would work if needed.
