I have killed roughly 10 bull elk and various other game with 165 grain X bullets from a 300 Wby. I recovered a grand total of ONE bullet; a mule deer that I shot facing me and the bullet traveled the length of the neck and part of the spine, breaking it in the process. All the rest were complete pass-throughs so I didn't get to see what they looked like. When shooting feral cattle and horses, pass-throughs were not the norm. Generally, a 180 grain X bullet would not exit but I never bothered to dig them out!
They sure do penetrate just fine. I don't think that is ever the question!
With a 300 weatherby you could shoot any bullet out of it and get a kill, different matter for a 30-30>Same goes for my 378 bee. I've shot lots of animals with every produced bullet from all the different manufactures and they all killed them dead.
