I recall watching a video long ago of a cull of a large herd.

Main rifles in use were FN49's in 308.

4 or 5 gents handled the FN49's, very fast action, quick head shots.

Two gents had large caliber bolt guns as "stoppers" in case of a 308 shot not making its mark or a charge by an ele on the sideline.

The FN49 shooters were very good, even jumping up on fallen elephant to have a better shot at those standing. Those big capacity magazines were a definite plus.
