A .270 will kill a S. TX Nilgai.

Last one I saw killed was with a Partition out of a .338 WM.

The guide likes .375's.

Where I hunt LA WT's, a .223 is an effective round. Other than youngsters, adults are expected to shoot something bigger. And, I do. I have an 8 twist .22-250 that loves 80 gr. bullets. It would be a great WT round.

But when in Rome...
