The perfect caliber for my first Buff will be my 500 NE!!
If I do my part and smash a Buff/Ele properly with that rifle I would like to do a later Buff/PG/Hippo/croc hunt with a 450/400 with a QD scope and a b/u 416 bolt.A qd scoped 450/400-- maybe a little handier and more versatile for other game than a heavy Double.
