I cleaned The 54 match thoroughly with Hoppes/Rimfire Blend; Kroil; and JB paste. Lots of black coming out with each cleaning.
I decided to take it to the range, and it shot dramatically better! Some 5-shot 50 yard groups were under 1/2".
Now the question is, "how much barrel cleaning can I do, and not harm the barrel?
You need proper equipment.Get you a rod guide. You won't hurt it with proper cleaning.

ALL the old lead and carbon out only shoot good quality target lubed ammo and you won't have this problem again. You will likely get your best groups after about 50 rounds of a good ammo the gun likes. You should get 1/4" or better at 50 yards. Wolf MT and SK Standard Plus are good economy ammo.
Glad you are getting it straightened out.
Here are some more ammo sources.
