"...Should you say good luck with that..." Not exactly. Finding dies will likely be an issue though. RCBS makes 'em, but only on special order and they're expensive. Retail around $161.95US.
When you're rummaging around the Internet, pay close attention to which cartridge the assorted forums are discussing. A lot of 'em talk about the 7.5 x 55 Swiss and not the Ordnance cartridge.
