A friend managed to kill a 152" buck in Ohio last year. We tracked him nearly 200 yds back to his bedding spot. I had never seen an animal go so far being shot as well as he was. This bedding spot was the area of his body and nearly a foot deep. It overlooked the entire farm where he could be approached and his escape route was nothing but briar patch on top of briar patch. Attempting to invade a mature bucks territory without him knowing you're there will be extremely tough. You are taking the chance of spooking him. My advice is find an area where you are seeing doe nearby and hold out for the peak rut.Hunt the area from sun up to sunset.Do not overhunt the area until then and be "SCENTFREE" everytime you go into the area. Make every attempt to not spook any of the doe when leaving at night. A doe will give up your position long before most buck will. You will need them to lure him out in the chasing phase of the rut. Just my 2 cents.
