This past weekend, we had a shooter come play with us with his factory rifle in 6.5 Creedmoor using Hornady 147gr factory ammo.

He complained that some of his shots were not being detected by the etargets. I noticed something strange about one of his shots and since I had seen this before, I set myself up properly and captured the following video.

Yep, that's what a bullet blow up looks like. Enjoy.

That’s interesting. What is his twist rate? Was this his first time using this ammo?

He said it was a 1:8 twist. New rifle. Very low round count.

That’s awesome! I think that’s what led to the Speer 125 grain TNT’s being designed with thicker jackets too. That might be how they got their name, but I’m not 100% positive about that. They used to have a maximum twist rate caution on the box.

My cousin experienced the exact issue seen there with 140 ELDs. Hornady said they weren’t aware of an issue but if you look on different forums, there have been many cases of it happening. Shame on hornady if you ask me. We fired the ELDs out of 3 separate guns the day my cousin was having issues. A Savage, a Ruger RPR, and my Tikka CTR. Each of them had the same shit happen. I honestly think the jacket was too thin and the high humidity peeled the jacket off due to friction. While the American Gunner stuff is good to go for cheap range fodder, the ELDs are garbage to me, no matter anyone else’s results. Berger has some good loaded ammo and it does what it is supposed to at a price very similar to loaded Hornady ammo plus you get to keep the snazzy Lapua brass once you’re done.

High-humidity air is actually less dense than low-humidity air. Plug atmospheric data into a Density Altitude calculator to see this.

Jacket design, jacket thickness, the way the barrel's lands are cut, the way the lands cut into the jacket, and bullet rotational speeds are the primary factors in a bullet's blowing up in mid-flight.

I’m going to use the blowup excuse the next time I have a miss. Wink

It’s obviously a problem, but thus far I don’t believe it’s happened to me with the 140 ELD and my TRG.

As for the humidity thing, I’ve actually seen the error published in books that were supposedly for long range shooters. But even though high humidity means less dense air, the difference in bullet trajectory whether it’s high or low is very minor at moderate distances.
