Distance is a known constant. If you know the distance, compensating for it is easy. Either hold or dial your elevation correction.

Wind is the changing variable.

As far as "ethical" distance? As long as the bullet retains enough velocity upon impact to reliably expand (HP) or penetrate (HC) and inflict enough damage to provide adequate terminal performance, the cartridge is up to the task.

That leaves the shooter as the deciding factor. My limit may not be your limit. Therefore, as long as I can reliably and consistently place my shots on target with a cartridge capable of the distance at hand...........honestly...........keep your "ethics" to yourself. Because, if the science is there and the ability is there........why not?

Just because you can't doesn't mean I can't.

No?
