We loaned him a 30-06 and 165 grain Trophy Bonded bullets. He had a 7mm-08 but all he had was "deer hunting" bullets (forget "Use enough gun", I say "Use enough bullet"). Shot him at about 50 yards and the brush exploded with nilgai running all over. Dropped him in his tracks with a neck shot. He's not a full grown bull, but big enough!
