David,
Thanks for the additional info. With the $25K from the NY Legislature, and $5K apiece from the NRA, NY City, and Brooklyn, that's quite a bit of money even today. Outside of the NRA, can't you just see the others coming up with even that kind of money today?
Roberts is pretty sparse on details of the Creedmoor range, other than what I wrote. He and his uncle were very interested in the first match and his uncle was said to have bet a months wages on the Irish team because he figured the Irish had the finest rifles in the world, and his thoughts were there was no breech loader being made that could shoot as well as, let alone better than, a good ML'er.
I don't really blame Roberts for getting mixed up on who could shoot for the Elcho Shield, since then, as now, there are so many various matches being held at Wimbleton that it would take someone very familiar with them to be able to sort out who could shoot what. I notice you're not even to sure!
About like our Camp Perry over here! As far as I know Roberts never went to Wimbleton , so I would imagine he got most of his info from the papers, which paid a little more attention to the shooting sports then. Usually tho the reporters sent to the matches didn't know much more than they do these days about shooting. "The Rifle" and "Shooting & Fishing" would make some pretty snide remarks about things that showed up in the papers of the day.
Your comments on the available yardage at Creedmoor is interesting, but still doesn't answer the question of whether the range was actually setup for 1000 yds. at the time of the challenge, since we both agree our sources say that the members of the Amateur Rifle Club had only shot at 500 yds., maximum.
