I did some testing with my own 380 Ruger .....ar 7'....five sheets of 7/16 OSB siding 2" a part ....went through 1- 4 and mushroomed and stuck in the fifth .... better than a dime in size.....winner to me!
If your ever attacked by 6 sheets your screwed. Shouldn't be a problem now because no one can afford 6 sheets at once anymore.
