I don't claim to be an expert long range shooter but I have observed the same thing as well. Not uncommon for a rifle to shoot 1 1/4" at 100 and shoot 1 3/4" at 200. I have done it a lot.

I have coached high school football for nearly 30 years and have seen the same thing happen to footballs when passed or punted. They will sometimes start off with a wobble then stabalize half way to the receiver or returner. You can't see bullet in flight but I can see a football.


Most people don't really want the truth.

They just want constant reassurance that what they believe is the truth.
