FWIW, I have no problem with anyone taking their .556 Tyranosaurus Special, if that's what you want to shoot. My objection is to guides and/or outfitters insisting that you must bring at least a .300 Magnum of some sort, especially if you don't have a .300 Magnum (or something larger) in your gun safe that you shoot regularly. A nilgai hunter should be free to bring whatever rifle he has that he has confidence in and can shoot well.
It's a vicious circle of ignorance.
One of my buddies had a guided hunt for Texas white tail, he brought his 270. When he returned to camp w/ a nice buck one evening there was another "sport" that had tagged a nice buck. The "sport" looked at the well placed shot on my buddies deer and asked him what he was shooting.
When my buddy told him he was using a 270, he sneered and said "that's what I started with as a kid." The sport let him know that he had taken his deer w/ a 300WM and was grateful for its "stopping power" on his "tough" buck. His deer had 3 bullet wounds, only one of which was marginally in the vitals...
My buddy's s guide told him later, quietly that their typical customer shot like Mr 300WM, regardless of what rifle they were using.
