If it's tight, just get a competent gunsmith or engineer to add a 'lead in' for the pellet.
Fanning about with rods and polish will be fruitless and could do more harm than good.
There was one we had in the warm, where after the initial nudge into the barrel, i could actually get enough speed for the pellet to exit by blowing down it.
