I use Unique for 9mm, H335 for 55 grain 223. I'm working on finding a load that my rifle likes with Varget and 69 grain bullets. Like everyone else has already stated, you have to be flexible with powder right now and use what you can find.
Using HP38 for reloading .40 S&W and have found it to work well. After reading the comments here, will buy some of the IMR 4895 for .223
