I dont know the answer to your question, but there was a thread on here a few days ago with the same question about accubond bullets. No blood trails. I had the same problem with 130 gr. Sierra pro-hunters a few years ago. We lost 3 deer in 1 year. Buzzards found them, or we never would have. Changed bullets and havent had any problem since.
Im surprised. My brother and I have used the Pro Hunters for quite a few years and they've been phenomenal. I will say that a bulk of those were before I bought a chrony and found the load we'd been using was pushing them about 2750 fps.
