My uncle has a 378 weatherby for 30 years and shot allot of moose he has a bushnell elite 2.5x10 and has had good luck with it. But know he feels like it isn't good enuf, he wants to buy a 460 weather for a grizzly bear hunt in bc. he's not sure what scope would be good to withstand the recoil of the 460, he dose not use a muzzle brake my uncles got a 1000$ limit for the scope
