hello, i was recently asked by our local SWAT team about giving them some plate to test for armoring-up one of their vehicles. i really don't know what grade to give them. i was thinking maybe some astm a514, i have some 1/4" laying around. any ideas? what they will do is shoot the crap out of it with various calibers and see if it holds up. ( i hope they invite me to the testing).
thanks,
JJ
