Wax lubed lead bullets leave the most soot.
Coated, plated, jacketed pretty much take bullet lube out of the equation.
Powders leave less residue when operating near the top of their useful pressure range and more at low pressure, just like a smoky fire in a cold wood stove leaves soot. Different powders leave different residues. Some leave a fluffy residue that cleans out easily.
As a reloader, I can pick my powder and reloads to suit my taste.
Now the bad news. You have no way of knowing what powder is used in commercial loads, and the powder may even change from batch to batch. They may even use a custom blend you can't get.
So if you find a certain batch of your favorite load is just what you want, buy all you can of that batch.
