Probably the best DIY hunt out there...
Anyone should be able to get a shot at a legal antelope...whether or not you shoot a big boy or not might be another story.
Antelope are active all day...they're curious creatures so they sometimes approach you vs. run off...
Great hunt to do yourself.
Get that rifle dead on at 200yds, and you should be good to go.
Study up on field judging them, they're very hard to judge...
