The BB gun will not do the job. It will either bounce off or wound. Get an air rifle that shoots either .177 or .22 pellets. I bought a Chinese rifle for $19.95 at a tool sale that shoots hard enough but not accurate. My buddy has the same gun and it is accurate enough. Go figure. I am considering a Gamo Shadow that is on sale at Dick' s Sporting Goods for $139. Probably get it this week.
