Those old books are great fun. Who or what is GOOP? How do I order from them? Your post moved me to get out my copy of Whelen's Mr. Rifleman. I have read, reread, and re-reread the chapters on the Krag. He sure makes me want a High Wall in 30-40 like his rifle Salina. In his book is a picture of the "First Army Infantry team at Sea Girt" in 1903. Many of them attached their slings to the stacking swivel and through the upper sling swivel forming a loop. Do you know that the Army no longer teaches the use of the sling? They have not since the M16. In fact it does not have a sling but a carrying strap. Whelen's book also has 2 chapters on teaching soldiers to shoot that he wrote in 1903. We were using the same time proven techinics in the 1980's when I was a Drill SGT, with the exception of the sling of course. It is fun to read and look at pictures of guy's in suit and ties, shooting prone. Krag lovers, if you can get a copy of Whelen's book DO.
