I'm relatively new to reloading. As a result, I don't have a large collection of powders.
I load 9mm, 38special, 357 mag, 380ACP.
My next gun will be 45ACP.
I currently try to use Bullseye for all of the above and plan to buy
WIN231 also.

There are few Bullseye recipes for 357mag in my three reloading books.
Is that a bad powder for this caliber?

it is not appropriate for "magnum" loads. You will reach maximum pressures before maximum speeds for the caliber.
Like many superfast powders it is also touchy at these pressures and very likely to jump them with any change of components or weather.

You can however load it to about 900/1100fps with lead bullets for very pleasant and cheap shooting.

231 will have similar characteristics

As stated, not optimum for the .357mag or even .38spec +P, but a great powder for mild .38spec and .45ACP target loads. It was THE powder for target loads in both cases for many many years. I use it exclusively for light .38spec cast WC loads and have yet to find a revolver that doesn't shoot those loads well. 231 has all of the strengths - and weaknesses - of BEYE, usable, but not necessarily optimal for all of them.

Personally, I tend to lean towards Unique for both the 9mm and .380ACP, in fact if you wanted just one powder for all of the cartridges you listed, I would recommend it as a first choice. It will get you decent velocities for .357mag jacketed loads, too. The only question is if it will be the preferred powder for each individual pistol and revolver. Odds are, some will like it a lot and others won't. That probably won't matter too much for practice loads at 25yds or less as they will all be on the paper, but if you are looking for optimal accuracy for each gun and the smallest possible groups, then you will very likely have to try several different powders (and bullets) to see which likes what best.

I found 2400 works great for my 44mag and 357mag.

Then I use Power Pistol in 44Spec, 38Spec and autos from 380 to 45ACP.

Try different powders, but always use the right tool for the job. One size dosen't fit ALL.
