I know you didn't, but it sure looks like the muzzle velocities and bullet weights were chosen to make trajectories for the three calibers look the same...
Oh, crap. I just realized that I used MV for a 110gr .277 load, with a 120gr bullet. :o
Will rerun the .277 table, using an estimated MV of 2600 fps.
Quote:We don't seem to be getting traction on the long range game with these choices. That's the reason I have advocated looking at lighter, smaller bullets for the assault rifle and thinking about a half-kilometer instead of a full kilometer.Considering the seemingly low probability of replacing 7.62x51, together with (as Gene has pointed out) the combined effects of short barrels, low-magnification optics, and the less-than-match grade accuracy of service ball ammo, I'm inclined to agree.
