How many grenades for metal doors?

So i had a shootout with a few neighbors of mine and am planning on retaliating. I have an explosive charge and 6 grenades. Will this get through a metal door? Also, how many grenades by themselves does it take? I’ve been seeing mixed answers and that the wiki is outdated or incorrect.

if the door is decayed maybe.But i dont think so.Better you search 2-3 more C4.Thats enough to blast the door away

I use 1 c4 and 4 grenades to take down a metal door. Works for me :smiley:
