Following on from bogwelly's question on case tumblers:
Sorry if this is the first of many stupid questions from a novice reloader; but how necessary it is to tumble or ultrasound cases?
I had intended to brush them out internally and hand clean the primer pocket and hole, but not clean them mechanically to shiny or soak them?
To start I will not be doing too many loads as it is only for myself and I will probably just do a few batches.
If I brush them out and clean the primer by hand then soak them in vinegar and water (if necessary?) will this suffice?
