Is factory 7mm Allen Mag even available? Or this that strictly a hand loading proposition?

I've had a 300 Weatherby Magnum since 2000 and bought one box of factory ammo that year. Shortly after, I bought 100 rounds of brass. Now I'm always cruising gun shows to see if I can pick up a few rounds of cheap 300 Wby brass here and there. Just the brass is crazy-expensive now. Factory ammo is around $60-100, depending on what make.
