I'm conflicted about the TTSX's performance in your report and my experience with them which has been very good in 7mm, 30/06, and the 375 H&H. No run-offs other than very short distances and most DRT. I have seen some narrow wound channels though and even through soft tissue (lungs).
I wonder if it has something to do with that weight in the 257? Or "that batch" for example?
