I was researching after reading Tactical Shooting (a very good sumplement, im my view, I recomend it) and trying to grasp what is a BB round, or Barrier Blind. After some time, I get it. But, one question turns up: Are Open Tip rounds considered Hollow Point rounds, GURPS-wise?

In Tactical Shooting (p. 79), descriptions of basic loads are offered. I noticed that under FBI and LAPD Officers, the ammunition of the Rifles (RRA LAR-15 and M-16, respectively) are HP-BB rounds. Some cross-checking done and I get that the type in question is a 5.56mm OTM (Open Tip Match).

I also read that Open Tip Match rounds are comonly used by snipers and Special Ops units, and, now, by the USMC as the Mk318 mod0. Better ballistics notwithstanding, I read that an Army JAG called for all snipers to stop using OTM rounds due Geneva Convention infraction, but the services made the point that OTM is not the same as Hollow Point, because do not have a expanding characteristic, I`m flumoxed!!! Could someone explain that?
