Mornings win hands down for me,,altho my best buck so far was killed in the afternoon..After the weather cools down & the rut kicks in I generally either hunt all day or until around 3 PM,,depending on my chosen spot..I' ve noticed that if I have an un~productive 1st few hours after daylight,,well,,around 10 AM I get th ol IBalls on full alert & lots of times the deer will be a buck at that time of day..
