Having shot NRA 3 position competition (albeit several decades ago) using a shooting jacket, glove and a bicep sling I have to say it was neither easy nor something mastered in a very short time. The Anshutz was out then but we were using heavy barrel Winchesters, model 52's I think. Later on (early 80's) I had my own anshutz but used it for .22 silhouette. I lost the darn rifle in the divorce, sigh.
