mista brings up a GREAT POINT here. You can only use the trajectory tables as a "general guideline" not as the gospel. Barrel length, actually attained velocity and line of sight to bore relationship is different on most guns.

I know some will scuff and most old writers who want to "show their education" poopoo the old "rule of 3" but its works for the most part. Most deersized calibers and bullets doin 3k fps, sighted 3" high @ 100yd will be "killin close" @ 300yds. The only thing to remember is that if you have a propensity to shoot em in the neck at 200yds, you will have to aim low as the bullet will be at its highest point then when sighted so.

I have umpteen rifles and for the calibers that shoot over 2500fps all but one are sighted +3" @ 100yds. The "exception" is an ol 30/06 that I will shoot on one particular trip in the big woods of southern MO in a couple of weeks. It is printing 180 Triple Shocks only +1.5" @ 100yds. But I will have 2 rifles on that trip and if I move to a field edge or anywhere shots are going to be offered over 200yds I will have a different gun.

WHACKEM where they stand,
