You'll see more antelope because they are out in the open during the day. They are a fun hunt. You don't need to buy expensive bullets for antelope. Remington Core-Lokt's, Winchester's base ammo, etc. will do just fine. Many people hunt antelope with .243's, 25-06's and 270's so any bullet size in .308 that you choose will be more than enough bullet. Have fun on the hunt.
