Nice, that that isn't where the name came from.
And where do you suppose "Creedmoor Sports" got its name?
And how did Creedmoor matches get it's name? And when you find that out, find out where those that came up with that name got their name.
If the guy that worked on the 6.5 had been the GM at Arby's it likely would have been called the 6.5 Arby, but he was GM at Creedmoor sports.
