I used a tornado brush with a drill. Each year on "sight in day" all these guys show up with their new in line muzzle loaders and plastic sabots thinking they don't have to clean them between shots. When their group goes to hell and the sabots start going down hard they start listening. When I shoot nitro and fiber wads the charge goes up about 10%. Years ago when plastic wads first came out it was recommended to go down 10% because they sealed better. Up your load about 1.5grs. I've shot fiber wads a number of times, and at skeet it didn't seem to make much difference.
