Went nilgai hunting with a good bud a few years ago. I had just had shoulder surgery, so watched him kill one with a 338 Win.
Guide carried a 340 Wby, liked big guns for nilgai, thus the .338.
From what I’ve read, a 200 NPT out of an ‘06 penetrates as well as as some of the bigger rounds.
So even those who think a nilgai blue bull is armor plated, the above combo should penetrate as well as a .375 or similar. Of course most deer rifles with a good bullet will kill one dead.
