This bull still with 'sharp' tips has more of a 'sweeper' shape. I have never measured it but this plus the next one are in my shed and I can measure them if I can find a tape measure

.

They were taken near the Wilton River in Central Arnhemland last year with Graham Williams of Australia Buffalo Hunters. The bulls in that area have more of the 'sweeper' characteristic with fewer having the more crescent shapes.

Both Matt Graham and Graham Williams are members of NitroExpress.com though are too much in the bush nowadays to drop in on us on the internet. I understand both have been busy doing a lot of hunting.
