I have a small vegetable garden and over the summer there will be small beavers rabbits chipmunks and other small animals in my garden. Do you guys think I should a slingshot to get rid of some of them? I currently use a store bought slingshot but I will make my own soon. I bought some 5/16 ammo for the slingshot and it was a mistake (too small) Do you guys think it will kill or injure a small animal. Also I have large deer that eats all my pine trees do you think a 5/16 in ammo will kill it if I nailed one in the noggin. Here is my slingshot Btw I am not sure How to hold this type of slingshot. The hammer grip really puts a strain on my wrist. There is a 5/16 in ball in the pictures.
