Donald, in the current high demand and low supply market, there is no eta unfortunately. I would start with contacting HenderShots : https://hendershots.net/product/280-ackley-improved-extreme-custom-ammo/

thanks everyone

Try the product locator on Hornady's site

NO ETA on availability. I recommend that you CHECK G(un)B(broker), they have a few 280 ackley improved ammo available. I hope this helps.
