Nobody is ranging either way on an animal with what can be called precision. People that talk about ranging with reticles as some sort of useful and used tool, are stuck in reading Vietnam sniper books. It don't work in the real world. When the there was no other way to guess at range (because it is a gues when you range with reticles) then milling was "used". It's only taught now as a last resort, emergency guesstimate of range so the spotter can maybe hope to pick up the trace off the miss for a second shot correction.
People that actually are prepared for milling targets on the scenario carry a Milldot Master or cheat sheet, or use their Ballistic Calculater. There isn't any hand jamming.
Exactly, measuring distance with the reticle is nothing more than a mental exercise. A LRF is a must for distance shooting.
