This probably won't be much help as these aren't easier to find but both the .22 WCF and the 5.6x35R Vierling are very close to Hornet cases with .055" nominal thick rims. Maybe opens up your choices?

Edit: Buffalo is out of stock on the .22 WCF but maybe getting on a notification would yield results? Link => https://www.buffaloarms.com/22-wcf-winchester-center-fire-22wcf.html
