I looked into the cost of the 50 caliber sniper rifle and Oh My Lord are they expensive.  So I looked into making one out of wood which is my solution for many things.   

 

 

 

Unfortunately this only shoots little rubber bands so not very effective over 2 meters and it was hard trying to get within 2 meters of the varmint.

So I bought a live catch rabbit trap.  A little lettuce, a piece of carrot and a small tomato for bait and within 24 hours I had Brer Wabbit captured.  I took him for a little drive in the country and released him where he can eat someone elses garden.  Not as satisfying as blowing it to pieces but a whole lot less messy.
