what state are you hunting in??? The states with blacktails in them, (OR,WA,CA) , have a lot of habitat where muley's and blacktails have intermixed and consequently do not have the genetics to produce monster bucks. A lot of the habitat of the Cascades is like this. So, if you are in one of those states, you need to get into areas where the muleys are pure. Montana has lots of bucks, and while they have no blacktail influence, they seem to have a smaller horn structure than some of the other states. There is some great hunting in montana for mid twenties bucks that score in the 160 to 175 range. To consistently find bigger bucks than that, states like Idaho, Wyoming, Colorado and Nevada seem to have the ability to produce bigger bucks. The true mark of a good hunter is to shoot the best bucks that your area has the ability to produce. And there are two rules that I have found that seem to help to get bigger deer, first, don't shoot the small ones, and second, the longer you are out in the field, the better your chances of running into something big. So, don't concentrate on morning or night, spend the whole day out there. But, if I had to choose, I would always pick morning. Simply because if you spot one, you have the rest of the day to go get him, the problem in the evening is that you run out of time a lot. I also wouldn't get to hung up on B&C score, look for mass all the way through the horns, and look at the width and height of a deer horns. If the width + height equal 50" or more, you have a great buck. Setting realistic goals for yourself will let you have a better hunt and also let you harvest an animal once in awhile. In todays world, a nice clean, 24 or 25", four point is a really nice buck for public land.
