I would use my 35Sambar, a 325WSM necked up to 358, very close to a358Norma magnum in performance. 225 or 250 grain Woodleigh Protected Point and 225 grain Hydros. The Woody 358 PP and RN projectiles I have found to be good for at least 200fps above their recommended impact velocity.

The 35 Whelen would certainly do the job, and a 358Norma even better.
