Actually you would be surprised how little is actually pushed down into or at the nipple. One of my rituals while shooting bench is to look down the bore after patching and before putting the charge down. While patching I do listen for the tail-tail sound ofdry air rushing through the nipple. With the stainless barrels I am using - I am also looking forthe reflection of the light coming through the nipple and creating a bore light in the barrel. I havenot everobserved a lot of loose fouling in the breech plug area or recession. There certainly is some hard fouling from the last ignition but that is about it.
Up until using thisWhite ithas not been necessary to clean the primer pocket or flash channel of the 209 nipples or to use a nipple pick (I am not even sure I have one for the inlines). They just keep on working and have never been a problem to put a primer in or get an expended primer out. With the White and
the old style of 209 nipple I have"q" tipping the primer pocket has become a necessity, other wise it is very difficult to get the spent primer out. I have a new breech plug/nipple that i will try this weekend - it is built along a more conventional typenipple. Should work a lot better.
