R=Russian. The Russians invented it for their Olympic rifles.
Many years ago when "Boots just finished his training for gunsmithing, he was still at his parents "sporting Goods" store here in Racine, WI. He had some items for sale in the counter. One was a tang sight for some lever gun , a chamfering tool made FOR RCBS, ( by L.E.Wilson) and marked as such, and a small red round container of BB caps from Stoeger arms. I only bought the tang because it was a piece of history, as were the BB caps. Sold the tang and still use the chamferring tool. When I go into my cabinet, those BB caps are still there. memories...
