I've shot deer and pigs with mine out to 675 yards. Apart from a yearling hind up close they were all one shot kills. Just remember they are target projectiles that happen to kill quite well at long ranges/slow speeds.
Your sample of examples is not really much to go on; there's miles too much talk on forums about good/bad projectiles without sound field experience to back up statements (no offence). One would literally need to shoot 100s of shots with a certain projectile before making a definitive statement about their performance, someone like Nathan Foster or Greg Duely...
I like them, my mate likes Bergers in his 7mm RM, we both haven't shot enough deer/pigs/goats to really say what's best... Both projectiles have seen deer run after been shot.
Use them they're great for long range, apparently...
