Not sure if the Brno 602 was ever offered in 416, I doubt it though. Mines a custom I purchased as is, its my favorite rifle.

And I don't think the bullets expanded much at all!?!? Not good performance from an "expanding" bullet if they didn't

I went out later and shot it with a Remington Core-Lokt 30-06 from my 20" barreled Ruger No 1 International. Bullet didn't exit, but way more flying ice and larger entrance hole, so I'd say it defiantly expanded that bullet.

Tempature was -27C at the time, and the ice sure seemed hard. Barrel was so heavy I couldn't tip it over, had to use the tractor.
