Actually the indoor range at the old Cooper facility was a bit less than 50 yds, the indoor range at the new facility is a true 50 yds. I have been in both of them at both the old and new facility and can vouch for the yardages.
Both rimfires and centerfires are shot at 50 yds the centerfires are guaranteed to shoot 1/2" 3-shot groups at 100 yds. I agree since the yardage is not stated on the test targets most people assume that it was shot at 100 yds.
