Here is a tip for efficiently dealing with raptors on foot.

You need:

1x Bow

3x Bolas (for a pack)

15x arrows

While the raptor charges towards you throw the bola at it. While it's immobilized pull your bow to about a quarter way, as this will shoot faster than pulling to full. Spam the quarter way strategy for really fast arrows? This should shred through most raptors.

This also works for other creatures!

I hope this helped!
