Thanks to Zeek for some clarification on the "FreeChec" and "Freechex" situations.
I know in the past Charlie has copped some rather uncharitable comments that he stole his "Freechex" principle from Paco which is quite obviously incorrect. "Freechex" creates gas checks to fit to gas bullets, "FreeChec" creates gas checked cast bullets. While the names are similar the principle is not.
