This is my first antelope. Shot her with a .257 Bob at 217 yds thru the neck. we sat and watched her for about 30 minutes(felt like hours). She started out at about 350 and just kept getting closer so I ket her some. She would have come in to about 100 yds or so but a buck started chasing her around...so I decided I had better take her before the buck runs her off for good.
