Recommending a substitute for any scarce powder is difficult. All of the popular powders are scarce and have been for over a year at least. You just have to take what you can get when you can find it.
Check your manuals and make a list of the powders shown for what you want to load. Then hit the stores and if you find something on your list, buy it.
Hodgdon is marketing Hodgdon, Winchester, and IMR powders. While some of the Hodgdon and Winchester powders are identicle even though they have different names, The Hodgdon and IMR powders that have the same numbers are NOT the same.
