I would definitely be more picky with my shots using a Berger or a GameKing , then with a mono or bonded. Not that I would go looking for hard quartering shots and pass up nice broadside shots. . I like using a bullet I can have the confidence to get the job done. If the OP’s Buddy is confident that the Berger bullet will work he can fill his boots .

Don’t sweat the petty stuff, don’t pet the sweaty stuff.
