Home Forums Hunting & Shooting Express Rifles and Big Bores Only CZ550 375 H&H.. What needs to be done to it?

I have a CZ in 416 Rigby. I slicked up the action, had the barrel ported, steel bedded action, Mauser heavy duty cartridge spring, jeweled tbe bolt, & added a barrel band. I topped off with a Swarovski 1.25-4X20 PH scope in removable rings. Following is a water buffalo that was killed with one shot. I followed with a safety shot to the spine when on the ground. CZ's work.
