If that's the brass you're using, you'll be fine. .335" would work with Lapua and the Hornady I have too.
Conventional dies, neck or FL, are made to put enough squeeze on the thinnest brass you'll potentially come across. Therein lies the rub: most of the time the die is squeezing brass more than necessary, and then the expander ball is left with the work of bringing it back up so the hole in the neck will be the correct size for seating bullets.
