Northwestern University girls brave freezing weather to go through a Home Guard rifle drill on the campus in Evanston, Illinois on January 11, 1942.
From left to right are: Jeanne Paul, age 18, of Oak Park, Illinois,; Virginia Paisley, 18, of Lakewood, Ohio; Marian Walsh, 19, also from Lakewood; Sarah Robinson, 20, of Jonesboro, Arkansas,; Elizabeth Cooper, 17, of Chicago; Harriet Ginsberg, 17.

The photo of these 19th century shooters is from Lindsay McCrum’s Chicks with Guns.

Evidently the ladies, too, competed in Schuetzen precision shooting matches with specially-made target rifles in which the shooter fired from a standing position, typically outdoors at 200 yard targets. The photo is small, but those rifles look like Ballards to me. They would have been chambered in .32-40, the preferred American target competition cartridge.
