I had a 72 year old retired Army JAG Col. in my office today and we were talking about shooting. He said that when he went to Army ROTC summer camp at Fort Hood in 1960 the recoil of the M-1 bothered him. The marksmanship instructors advised those cadets to go to the PX and purchase packages of sanitary napkin pads such as Kotex, and wear them under their fatigue shirts. Actually, that's kind of a good idea that you could use at a sight-in day or a clinic like Appleseed! Sounds silly, but I can see that it would work!
