I was always told to wipe the bores free of any oils before use, although I will admit to seldom doing so. I believe these instructions come in most owner's manuals, but the reason why is never given. One thing I've noticed with no consistency is that sometimes powder will really accumulate in the bores, particularly right in front of the chamber. I've noticed a lot of fouling before, but then I might or might not notice it to be less after the next shot. I was shooting a Parker 12ga with RST's recently and thought the first 3 or 4 inches past the chamber looked like a Chia pet was growing inside. I was wondering if the powder, soot, or whatever it is probably absorbs the oil in the bore. Under the right conditions, could this build up result in enough of a "partial obstruction" to cause a pressure spike or other such problems?
If you think this is a stupid question, then please keep that thought to yourself.
