This will work it will also work for cleaning the metal preservative out of the new barrel use a copper brush.
The new Hoppes Elite and Montana X blackhorn cleaner also work very well.
Borebutter is for traditional rifles shooting PRB it is not wise to put it in your inline.
Do not use soap and water to clean after shooting Blackhorn that's for 777 and Pyrodex or Black powder.
Do not try muzzle loader 209 primers with Blackhorn they are to weak you need regular reloading primers they are not only much better they are much cheaper.
