Here is a one minute video of my hunting buddy shooting an antelope at 75 yards.
Earlier I shot one at 50 yards with a custom 7mmRM that I practiced and practiced out to 500 yards.
Over the years I have wasted too much ammo shooting at running antelope. I give up. Practice out to long range. Shoot at close range. Don't shoot when they are running.
There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway The man who makes no mistakes does not usually make anything.-- Edward John Phelps
