No, I said 5.7x28mm bullets do not fail to expand/tumble/fragment in gelatin testing; I was directly responding to another poster who tried to reference the purported 5.56x45mm failures, which were actually attributed to 5.56mm bullets failing to tumble/fragment.

That poster cherry-picked loads to make it appear that way (and admitted it). The 9mm FMJ test he posted was also done by a different tester in uncalibrated gelatin. We can make his comparison valid by using high quality 5.7x28mm ammunition alongside a comparable caliber (9x19mm):

9x19mm Golden Saber

5.7x28mm EA Pro II

The tests aren't quite to scale (the 9mm video is zoomed in much closer), but the tests were conducted in the same media by the same independent source (Brassfetcher).
