A buddy and myself have a Nilgai hunt on the book for late November. This is what our guide provided:
When hunting Nilgai, one will want to use a premium bullet. All copper preferably. We have
had very good luck with the Barnes Vor-TX ammo or if loading your own, then load the TTSX or
LRX bullets. The Berger "HYBRID TARGET" works well also. Federal Premium with the gold tip
has proven to be good.
Of course, any round and probably any caliber will take a Nilgai with placing the shot in the
perfect place. But we have found that even with the 6.5 calibers and using the Barnes TTSX or
LRX bullets that the bullet will go through both shoulders on the fully matured bulls.
We are taking a 300WM and a 338LM. Going for a bull and cows. Going thru with LOMAS CHICAS OUTFITTERS. Be practiced in shooting up to 400 yards off of sticks. It's hard to move a bench around.
