How Many Fruitcakes Will a Bullet go Through?

One of my favorite Youtube channels is 22 Plinkster. Every now and then, this .22 caliber trick shooter will play around with a larger caliber, just for the sake of blowing something to smithereens. In fact, he already did this experiment with a .22 and the bullet only when through 2 fruitcakes and the bullet was lodged in the 3rd! As a fruitcake lover, this was hard to watch...but very fascinating! How many fruitcakes do you think at 45-70 bullet can penetrate? Watch and be amazed!
