If you are looking for score....MASS is a large chunk of the total score. P&Y standards are pretty easy but B&C is ver tough. Grimmett's video is a good starting point but the bucks in his videos are likely several steps above reality to most Western hunters. Your best bet is to take a scouting trip to your unit and look over as many bucks as you can. I'd also go to as many taxidermists in Utah as possible so you get an up close view of bucks from your area. You might even take along a tape to measure bases, prongs, length, and 4 mass measurement quarters. There are gobs of antelope photos on the internet (including this website). Good luck!
