The reason Hornady no longer puts the load on the box is they no longer use H4350 and use a non canister powder not available to the public. One of the original requests of the guy who helped develop the creed was they use a canister powder and put the load on the box.
I believe they quit putting it on the box when powder supply became spotty. They addressed having to find alternative powders on their podcast.
Like many of us have had to do. Over the past few years I've changed several loads I'd used for over a decade, even longer. The only real positive is that I found some powders I hadn't used, that are working out just fine.
