This load is still on Hornady's site, even passing through the new site transition, so I'm prone to assume it is still a current catalog item.
However, it's 22mag, which is relatively unpopular, so it's only natural to expect 1) low production volume, and 2) short duration production campaigns. Being a critical defense line product - a defensive load - where the 22wmr is rather poorly fit, there is even less demand.
Hopefully you find some soon, or an alternative load to suit your needs.
