Late to the party with a grand sample size of 1 ~ 90lb whitetail but here you goes a lot because I enjoy talking about this stuff.
3040fps at the muzzle from a 243, shot distance was sub 50yds on a driven hunt. Figure out impact velocity on that if you need but we'll say it was objectively "high". Had a less than perfect shot opportunity when it stopped in about a 6 inch gap in the honeysuckle. Shot impacted right in the backstraps just forward of the end of the ribs, see picture. Somewhere in that 1.5" range for neck length and then complete destruction. It seems that roughly half of the bullet went into the spine and stopped somewhere in there, and the second half either blew or deflected downwards and completely shredded the nearside lung vertically.
I don't have a picture of the actual lung but if you were looking down at it, and then about halfway back made a cut longways through the middle of the right lung, that's what it looked like when we pulled it out. Right half almost fine, left half a bloody gelatinous mess. That continued to the left lung where it shredded all of that in a 3-4" path of destruction and then the "bottom of the cereal bag" pieces of jacket and core laid to rest with nothing exiting but they did make a nice little hole in the offside of the ribs (first picture). The only notable piece of bullet that was recovered was about half an inch long and a quarter inch wide (from memory don't quote me) bit of mangled jacket.
I would use them again with no qualms, but again sample size of 1 (one) 90lb whitetail.
My only note for the second picture (entrance side) is that this wasn't taken in line with the path of the bullet, you'd need to see it from the left and a little further down (camera pov) to follow the path of the bullet. I say this because from here it looks like the hole is wider left and right (camera pov) than it actually was. The vertical tear (camera pov) would be mostly unchanged
