Good question, not to sure on the durabilities of these and what types of rounds they can stop. My feeling is that it may punch through but this is pure speculation on my part. I am sure there are guys thattest this on youtube.

@@MaxCherepenin Thanks for the reply.. I watched a video on KZfaq on what happens when ammunition gets caught in a fire. Not much it just explodes like a fire cracker, yes the bullet fly's a little but nothing compared to being shot out of a rifle... Have a great day and thanks
