I had the opportunity to hunt with a friend that leases the Kennedy ranch that is not part of the trust. Took both a 7-08 and 308 using 140gr and 165gr accubonds. Used the 7-08 on a Nilgai bull and the bullet was retreived in the offside hide. Lung shot, he went 30 yards and died.
My brother shot another bull with his 7 mag after we spotted and stalked him and dropped him with a neck shot.
Keep all the meat you can, its good stuff.
