I never pay attention to the "legal" shooting times. If I can make a clean and quick kill then I will do so regardless of what the book says.
Personally, I think its rediculous. Anyone go over the speed limit?[&:]
EDIT: Thinking I should just add this to what I said above.
If I can make a clean and quick kill AND see through my peep...
Don't want anyone accusing me of shooting deer at midnight.
