bullet

Hi! I was looking to see if anyone could help identify this bullet casing. I found it inside of my bathroom wall while redoing it, the house is very old so I have no idea when or how it got there.

Hi, I saw a diorama with bullet holes on the plane wings. I was wondering if there is a guide that I could follow to make realistic bullet holes coming from underneath the plane with metal tear? if I use a drill it will come out as very smooth holes and not realistic looking. Thanks for...
