Yes, we do. I've had the same positive results that you have had; just not every time. And yes, I was using their hunting bullets. My main argument is their consistency. The bullets differ from lot to lot. You never know what you're going to get because lot #1 may shoot differently than lot #2. Even the most die hard Berger shooters will admit to that. My biggest problem with them is expansion on impact. I made (what I thought was going to be) a perfect double lung shot on a whitetail doe and it literally blew up on the hide. There was no penetration whatsoever. I might as well have thrown a firecracker at her.
Interesting. I will have to keep an eye on that lot-to-lot consistency. I purchase mine in bulk from a major ammunition manufacturer in my neck of the woods, so I end up getting hundreds from the same lot. I had just the opposite result of your whitetail doe on my bull from last year. Expansion was delayed, leaving a small entrance hole, and wrecked internals. Enough of the bullet held together to exit through a far-side rib. My results seemed consistent with those found in the Barsness article.
There are failures with just about any bullet design. I have killed a bunch of critters with Accubonds, and really like their performance. It is usually boom, and the game goes down. However, I shot my biggest bull with 200 grain .308 Accubonds, and it took four rounds. At first, I was disappointed with my own marksmanship. Then, during necropsy, it turns out all four punched holes through the lungs, with fairly narrow wound channels. Usually Accubonds leave the lungs in ribbons. I chalked it up to an anomoly, and the fact the bull was 900+ pounds on the hoof.
Even after that experience, I would use (and have used) Accubonds with confidence. Accubonds have worked as advertized farm more often than this one-time mediocre performance.
I also had an acquaintance tell me he won't use Accubonds, because he blew one up on the shoulder of a cow, but I suspect it was actually a ballistic tip.
I certainly agree hunters should use what they are most confident with.
BTW, I have never had a Barnes TTSX failure ... but I have heard rumors of them failing to open. They have all been quick one-shot kills for me.
I appreciate the conversation, Elkoholic307.
