It's enough to go through a anti matter drop ball. However, after penetrating through the ball it tends to slow down a lot, although it can still penetrate enemies after. It can also penetrate through most doors easily.
Dude, U don't really notice punch thru, it ragdolls enemies so they all bump in to each other and die.
Dude you could also maybe consider shooting through geometry.. That doesn't exactly ragdoll now does it? I would very much like to know an answer to this question as well. My guess from experience is around 2m but some legit data would be nice
All I know is that the MK-1 Paris has enough to pierce through four lancers. Hope that helps.
since this thread is over a year old, no, it doesnt help.
