An RPG round weighing several pounds arriving with a velocity of 2-300
m/s 
has quite a bit of kinetic energy to apply, and all of it concentrated
at 
the point of the nose which is usually less than an inch across... and
once 
the point breaks through, it takes far less energy to widen the hole
than 
it would to create an instant several-inches wide breach.

Don't bet too much on that. Several types of RPG rounds - I'd expect all
of 
them, but don't know that for certain - are equipped with a biting edge
to 
ensure that they don't glance off even if they hit at quite acute
angles... 
and while those biting edges are there to increase the chances that the 
round will detonate successfully, they also greatly improve the rounds' 
chances of smashing through thin obstacles if they fail to detonate
properly.

...you'd better pray that you are inside the round's arming distance so
it 
won't detonate	(or that it is a dud, giving the same result), because
if 
it does go off you'll get killed yourself when the round's rocket
booster, 
fin assembly and all other parts located behind the warhead come back at

high speed and hit you in the face.
