No stupid questions here :-)
Unfortunately you’re kind of stuck buying at least three different powder types. 45 ACP requires a fast burning pistol powder, I like to use Bullseye, since it’s pretty economical to load.
The 7.62x39 and .223 Rem both need a rifle powder, you might look at IMR 3031. Just know that those are two very different calibers with different powder burn speed requirements, you really using a sub optimal powder for either load.
For 22-250, honestly it requires a slower burning powder to perform well. IMR 8208 or IMR 4895 is a good choice, and can be used in 223, but not 7.62x39. You can also use both of those powders in 243 WSSM.
