The illustration below of a Red Hartebeest, with anatomy similar to that of a Blesbuck, shows that a centre body shot behind the shoulder usually results in a running animal. The safe body shot on species with this anatomy structure is below the horizontal centreline and on the shoulder, if the shot is taken broadside. I prefer quartering shots as it is then possible to place the bullet path through the vitals while not hitting either shoulder.

African Hunter Magazine.
GS Custom Bullets, situated in Port Elizabeth on the East Coast of South Africa,
manufactures solid copper, turned, monolithic bullets for hunting and sport shooting.
These bullets are used by hunters on several continents, hunting from the smallest of
antelope to the largest of dangerous game, using the smooth HP bullet, as well as the
more popular HV, FN and SP bullets with the patented drive band concept. GSC bullets
are configured for the highest possible ballistic coefficients. SP bullets are mainly
used for sport shooting. All GS Custom Bullets are moly coated.
