What wobbly said...
If you're leery about shooting it that first time, what I have done is to find a downed tree and after loading the gun, put the buttplate against a branch and strap the gun to the log. Tie a long string to the trigger, cap the gun, and stand behind a big enough tree that I could hide behind and pull the string. Didn't have a problem and shot the gun from then on with no uneasiness.
