I've shot more elk with a 338 than all other cartridges combined. I always used 250 grain Nosler Partitions. Different versions depending on decade.
Having said that, I've sold my last 338 Win Mag (I've had 4) and a couple 300 Weatherby rifles. I'd use 180 or heavier Partitions in either of those and feel 100% comfortable.
But I know people that use 270's and are happy with those. I am not confident in being able to get a perfect broadside shot.
