I have missed some easy shots and I know George is right I have wounded some rabbits but 95% of our shots are behind dogs.I'm shooting a lite gun my guess 4 lb gun which is more of a handicap than the 1\2 oz.you have to be locked on the gun or it moves a foot when I pull the trigger.
Two years ago I missed 7 rabbits in a row before I finally figured out you have to be locked on the rabbit....with a 12 you just need to be near one
