I think the ranch a fellow is hunting has so much to do with the success rates and quality of bucks taken. I have some friends who have been hunting the same ranch for years, and they have spectacular success each year. They buy up all the tags, and are the only hunters the rancher allows on his property, year after year. One of my best friends is in this group, and the last three years his bucks have been 35 1/2"5x7(2009), a 28" buck that scored 195" (2010) and last year he shot a 33" buck the first morning that grosses a big over 200". They usually go 5 or 6 out of their 8 tags, and the bucks are all real nice, or they simply don't get shot.
However, they are hunting a pretty special property with ample water and food, including a few hundred acres of agricultural crops on the property.
