I was reading the "Sportsmen's Review" coverage of the 1945 Grand. The observation was made that the scores were uniformly low, and the magazine attributed that to the lack of practice and the use of reloads. The reference to reloads threw me a bit inasmuch as the casualness of the remark made it sound like reloads were no secret and not uncommon. I didn't think that reloading caught traction until the fifties. Can anyone hazard a guess as to where the components might have come from, in war time, no less?
