Some time back there was a posting on here which raised my interest, the person posting was mentioning that the bullet fired from his rifle would have hit the ground in several hundred yards over flat ground.
This evening I took a few minutes to see just how far a bullet from my 308Win would travel before it hit the ground. I made a lot of assumptions as follows: the muzzle was 5 feet from the ground, the zero was at 200 yards, it was a 150 grain Hornady Spire Point leaving at 2800fps, the target was level with the muzzle, (i.e. the rifle was tilted neither up nor down) the ground was perfectly flat etc.
However, the 60 inch drop happens in just about 520 yards under those rather artifical assumptions. Changing my zero to a 100 yard zero puts the impact at just over 490 yards so not as much difference there as I would have expected.
I guess this is of some interest to those who shoot over flat fields and the like and it is certainly of academic interest.
