Well I have only hunted Nilgai twice, I shot both of mine with a 338 Winchester and 250 gr Nosler Partitions. While on those two hunts I saw several taken. One was with a 375 H+H another with a 30-06 and well 338. These days, your main problem is getting a good shot, they tend to chase them a lot with trucks and such. I shot both of mine on walks after lunch. One next to an water hole was very memorable.
