I just want to throw in a little positive criticism, if you plan on making it ‘realistic’ i would definitely dig into doing some research. For example you said from all era’s, in your video you start off with WW2 footage, the Mauser 98 (kar98) was designed in 1935 based off a round from from 1903. Even compared to modern rifles the Kar98 still has one of the flattest round trajectories ever made most modern rounds fired dont even come close at ranges past 400 meters. For comparison purposes the M16 had a MOA of 2.094 at 200 yards, while the while a Kar98 has on average a 1.25 MOA. At the same range an 1800s black powder muzzle loader has an MOA of 1.24… Do you see what im getting at? just some food for thought.
