I have shot my fair share of camels for both pet meat and also wild dog baits.
I used a 308 but would have prefered a 338 loaded with 250 or 300 gn projectiles.
Most of my shots were under 100 yards so bullet placement was good,however I would not try to shoot camel at distances greater than 100 yards using a 308.
They are tough and will travel a long way if badly hit so better to use a heavier calibre and get good penetration.
They are a heavy boned animal.
