ok one last thing, about the 175 gr. trajectory
175 gr. Nosler Partition @ 2400 fps
zero @ 100 yards
bullet drop @ 150 yards = 1.8"
drop @ 200 yards = 5.4"
drop @ 250 yards = 11"
energy @ 250 yards = 1600 ft-lbs
For comparison, a 140 gr. @ 2850 fps drops 7.3" @ 250y and lands with 1750 ft-lbs
the 175 gr. bullet was a great killer of very large game when loaded in the 7x57, which fired them at 2300 fps. Within 250 yards (further than most shot opportunitys), the 175 gr. will do just as well as the 140 gr., and maybe better, with the deeper penetration.
