Barnes lists the minimum expansion velocities, and for safety sake, I add a couple hundred fps to their value! I make certain that my longest shot is within that parameter. That’s not a problem for me……with my cartridge/load, that velocity window is 300 yards beyond my self-imposed 600 yard limit!
Though, even with expansion only to bullet diameter (Barnes claims 1600 fps)…….I still making a minimum hole size of 3/8” @ 1200 yards! 😉 memtb
Do you actually know what an "!" is for?
Barnes and any other mono is the worst choice one could choose.
