Hello there, I kept it very basic as most people wouldn't know what I was talking about if I talked plainly.
Yes, trajectory is the name for a projectile in flight. It's really interesting to to watch a long range shot through the scope as the shooter, one can actually see the bullet trace, the projectile, arcing downrange to the target if the environmental factors are correct. It's satisfying to watch the projectile land on the target.
If you want to see it you can on YouTube. If you fast forward to 0:34 on this video there is a very good demonstration videoed through a spotting scope. If you watch to about 0:54 you'll see some more.
A lot of science goes into shooting at long range which is one of the aspects I like about it the best.
Anyway, thanks for your comment.
I found it very interesting. Yeah! I agree once I was there looking at the people shooting they were very happy once they shot the target. It feels like a success if I were in their shoes too. My foster father in Germany loves hunting also that's why I had a little information about it. It has been added to the information you've shared as well. My pleasure, don't mention it.. God bless.
