Aside from the lube collecting dirt and assorted contaminants it can cause other slight problems. When a case fires it rapidly expands in the chamber and against the chamber walls. The friction prevents the brass case (or any cartridge case) from slamming full force against the bolt face. Will a lubricated case have the same friction as a non lubricated case? Also, as mentioned, the lube attracts contamination and we really don't want to spread contaminants around our chamber walls, not if we can avoid it anyway.Why do we remove all of the lube?

Shootsm there too much evidence to the contrary: from the relatively little energy adsorbedThat 'myth' could cause grief one day
