Most copper solvents work ok on powder, and carbon fouling too, seldom are powder solvents or carbon solvents effective on copper.
I have used a rotation of solvents in the past, with an ok result.
Then I found Wipeout!
You don't need brushes, a drawer full of solvents. 1 can, and just spray it in the bore, let it sit over night, and your rifle is clean(maybe twice on ugly dirty rifles)
To answer the OP: Bore solvent and bore cleaner are basically synonymous. A usually liquid compound used to clean the bore. As stated above some work on all forms of fouling, some do not. A copper solvent would be one which targets copper fouling, though it may also clean powder and other fouling.
Most bore solvents/cleaners, are designed to remove powder fouling, but are not very effective at removing copper fouling, even though many claim to remover copper fouling. It can take several days to remove copper fouling with most general purpose bore solvents that do claim to remove copper fouling, but the best copper solvents, like KG-12,CR-10, or Sweets 7.62, can remove pretty significant copper fouling, in less than an hour.
