Lee Shaver, a prominent and well respected gunsmith and shooter in the U.S, recommends a technique using 0000 steel-wool to clean badly fouled barrels.
Basically, step 1 is to run a tightly oiled patch through the bore a few times. Then, unroll the steel wool and cut a piece roughly the same size as the patch and place it over the oiled patch. Run through the bore, it should be tight enough that you need to "bump" the cleaning rod to get it through. Repeat. It may take a few goes but he reckons he can clean the worst bore in about 15 minutes. He even now uses this method to "break-in" new barrels for black-powder shooting.
He states that the steel wool wont damage the bore in the barrel but merely "polish" it.
Also, once you get your bore clean, I suggest that you "slug" it to determine the actual bore diameter. Those .310 cadets can vary a lot in bore diameter.
Once you know your actual bore, you'll find you will get best results with a cast bullet about .001" to .002" over bore diameter.
