Hello, I have had this idea in the back of my mind for years & finally decided to do something about it. I have always been interested in the long-range matches of the 1870's at Wimbledon, Bisley, and Creedmoor. I started digging and found a book in my library, Americans And Their Guns. It has detailed information on these matches..in fact in their day..they drew more crowds that the Superbowl of today!
There were detailed dimensions of these huge chilled cast-iron targets which were imported from England.
The earliest had a square bullseye, later changed to round. They were wider than tall, due to the military influence on shooting..It was thought long-range fire would be used against lines of infantry and artilery emplacements. A shot that was off on windage would still have a good chance of hitting someone, while a high or low shot would probably be a miss. Working with a printer friend, and a computer, these were precisely scaled down 1/10 for shooting at 100yds. with .22 L.R. Both the original square and round bullseyes were printed. The bullseye on these scaled targets is 3.6" I don't even know if I can see that thru irons at 100yd. Perhaps I will even try to contort my old carcass into one of them fancy back-position's of Creedmoor days. All this anticipated fun will have to wait until spring, as range is buried in snow & it's 3 deg. outside!
