No need to drop a weight class with these
We do a 165gr 308 that the FC have been using
They have been tested and expand reliably down to 2000 or so fps (equivalent to a 600yd shot)
The fad of driving non lead monolithic faster and dropping a weight class to get higher MV was a response from manufacturers who were experiencing poor terminal effect and unreliable expansion.
The Classic hunter is not designed with BC and paper marketing in mind
It's a blunt instrument designed to kill game effectively inside 300m, which is where 99.9% of most game are shot
Inside which the BC is largely irrelevant.
Nice clean carcases though!
