Ordering an ammo box. What size?

[Octane]

I'd like to order a couple of plastic ammo boxes (from Cabela's) to take to the range. I have a completely noob question: If I shoot .40 S&W, what size (caliber) box should I order?

They don't specifically offer it in .40 S&W. Options are: 380/9mm or 38/357.

Thanks!

Midwayusa.com got the lowest price, for 40SW you can buy for 45ACP/10mm/40SW same box $1.49each
