I have always wanted to program an Olympic Games sim, and I decided to start off with the simplest events -- the 10m and 50m air rifle competitions. I made a prototype using the rifle from DarkMatter, and it worked pretty well, so now I want to make a full version with real competition air rifles.
To start off, I found some images of real match-quality air rifles and picked this one to start off with.
Walther LS400
Attached is an image of my model from a few different angles.
