17 MILLION ROUNDS! Long-time @winchesterrepeatingarms employee John Riedel at work targeting rifles in the Shooting Gallery located at Tract C-84 of the Winchester Factory in New Haven. Some days, Riedel would shoot as many as 250 guns, five shots through each. He would eventually test-fire an estimated 17 million rounds or more through Winchester firearms before he retired from the company in 1943. He reportedly regretted having to leave during wartime production, expressing genuine concern that every firearm leaving the factory needed to be exactly right, a feeling of personal responsibility that was undoubtedly shared by many or all at the time.
