A real long read!

Hello, I'm the author of the 5.56mm Timeline. I apologize for not updating it more frequently, but circumstances haven't given me much time in recent years. When completed, the next update will contain a large amount of material culled from the Project Manager-Rifles' Weekly Significant Action Reports along with the Ichord Subcommittee hearings transcripts.
