I think a 50-yard zero is probably not optimal. Consider the ballistics of the bullet you're using. For example, the Hornady 500 gr 458 RN at 2050 fps gives these results, rounded to the nearest whole inch (who cares closer than that?):

25 0
50 +1
75 +1
100 0
125 -1

Based on these numbers, my 458 Win Mag is sighted in one inch high at 50 yards. I'm confident shooting it to more than 100 yards.

Many people complain that predictive ballistics are useless, but I disagree. Calculated trajectories often fail to coincide with shots fired for "ground truthing," but not by that terribly much. The predicted trajectory gives you a place to start, to be followed by many shots fired in practice and confirmation.







Well if that's the case it seems irrelevant what distance the rifle is bench zeroed within the 25 - 100 yard range. Only an inch difference in point of impact shouldn't matter. The lott is a tad flatter shooting. Bullet diameter is near half an inch! Sounds like its time for alot of practice and some unorthodox skills to be aquired, as in the shooting drill previously described. Good idea BTW. I think I can run fifty or so yards. I suppose i should carry the rifle, right?
