To successfully hit targets at long range, skill and capability must be present, and the rifle, ammo, optic, and any supporting gear must be right for the task.
I definitely agree with their thoughts on magnification and objective size.
Does bug that they used the term “gather light”, though.
Lenses don’t “gather” light—they don’t pull light into then (unless someone is using black hole lenses…); they just transmit light that strikes the lens.
