Personally, my traditional rifles are all given a VERY HOT WATER BATH with some Dawn Dish Soap in it. I want to make as much water rush through the breech and out through the bolster or vent hole as possible. It is the one sure way I know of to get all the fowling out of the end of the rifle.

A person came to my house once who only patches his rifle clean. Before we shot I asked him if he had run alcohol patches down it to remove the grease. Since he had not, I offered him some and low and behold the fowling that alcohol brought up, though not much, it was some, and that was sitting in the bottom of his rifle.

So in answer to your question, YES, I would do the water bath thing every time I shoot the rifle or as often as possible. Saying that, I need to go clean my Lyman Trade Rifle. I just got in from the range.
