I went shooting earlier today, and I had a few rounds of Remington Thunderbolts to waste, so I aimed at a snowbank about 200 yards away. I guess it's because I was shooting against a pure white background, but I was able to watch the bullet along its trajectory to the snowbank. Very cool!
I know shooting my pellet gun, which is probably about 300FPS, I can see the bullet if I shoot into the air, but this is the first time I have seen anything faster. The bullet sure does drop at 200 yards!
