There have been a lot of ethics issue threads here lately and I am surprised to see that this thread got all the way to AZ and Johnny before anyone said anything against trying to shoot two deer with one shot!
Not seeing a deer standing behind another one is one thing, purposely trying to make this type of shot is another!
The odds of wounding one or both deer are too great and attempting this typs of shot is by all means unethical! This is truly the type of thing that gives hunters a bad name, and there is no way to justify trying to take two deer at one time!
