I hope I am following you right, you want to have a match over the net. Like make up events and rules and have thread where people post their targets after they shoot. A week long thing were you have to have your targets posted by a certain date or time?
For the handgun part, use 1911's of course cause they were his favorite but also for everyone that doesnt have one an auto class as well would be cool. Maybe you could make a target that you have to hit certain areas for scores. Not just a round bullseye but maybe like half and a quarter bullseyes that you can print out and put up at 15 yrd or something, and put two shots on each target and then score them.
You could have like 5 targets to print out. 1 regular Bullseye- 1half bullseye- 1 quarter- and then we could maybe come up with something else of a challenge. I dont know how to regulate it (on an honor system) or if you would want a time limit per shot group or if you wanted, with each target make you have to do something like one you pick the gun up off a table shoot, then on one draw and shoot, maybe load a mag chamber a round and shoot at one, ect. I think it could work.
Am I trackin? is this what you are getting at or are you talking about a real match located somewhere.
