I shot donkey and horse for human consumption in the early 70's and used a 243.
We were paid 4 cents per pound for quartered carcases.
At that time a drum of fuel (44gal) was $22-00 and a new Ruger M77 in 243 with a Leupold 2-7 scope cost $159-00.

I shot roo's for a living with a 243 and recieved 45 cents per kilogram in the late 70's

Today for every 20 tons of roo carcase,a processor might take one ton of camel carcase..

The logistics of shooting ,processing and transporting camel to a processor is a logistics nightmare with little or no financial return at the end of the process.
SO WHY BOTHER.

Best calibre for camel is from 270 upwards.
