Lead fouling on cleaning patch

 What is Severe Leading?


Occasionally loads are described here as producing severe.

First of all, a description of severe leading will be qualified to a single load/firearm combination. A load that produces zero leading in one gun may turn another gun's bore into a sewer pipe.

This amount of leading is considered to be severe.  It is beginning to accumulate everywhere, in the corners, in the bottom of the grooves and on the tops of the lands. At this point things will begin go deteriorate rapidly. This level of leading was produced wit only 20+ rounds of a load with an undersized and under lubricated bullet.


In this case, accuracy deteriorated about a third. Three inch groups opened up to four inches.
