Trophet1, ive cull shot them on foot and from vechiles. Used mainly .243 and 100 grainers, 308 and 150/180's. The best knock down calibres i have hunted them with have been the 300wm , 338 wm and the 375H&H. I prefer the 338 with 200-250 projectiles. Partitions work well. Donkeys and camels can carry shots .
I run a 264 wm and would have no problems considering it for camels, hope to hunt them later in the year with the 358win and 264wm .
They are great animal to bow hunt.
Take the lead animal out and they will mill around. Hope this helps Mick
