Do you hunt on a full moon ever? Ever had any luck?
All the time. Western tags have fixed dates. You hunt or you don't...
On average, I'd rather a hunt not be on a full moon, but you gotta be out there regardless.
Midday can be ok as JG said but if weather conditions are not conducive for a midday feed (too hot or windy) you're likely left with hunting bed switches as the sun comes up or switches aspect after midday or a bedding change of the wind shifts.
