Usually it is from the Vietnam Army issued M16. They had slow twist barrels “1-12/1-13/1-14” and were shooting 77gr fmj. The bullet being too long to be stabilized and they did in fact “tumble” or more likely fragment upon hitting something. Military woke up and changed the twist to “1-7”.Correct. Bullets do not “tumble” as they would not be accurate. Not sure where he was going with that.
Just odd to read these days.
