Amazing, that is a lot of mass at that distance. How much will the bullet drop at 275 yards?
You’re pretty much lobbing it in at that distance. Still wouldn’t want to be out there with a catcher’s glove...
About 180 pounds depending on gravity and whether he is standing....
Mass does not change the drop rate - though drag will. Drop is only dependent upon the gravitational force applied. Drop a cannon ball and a fishing bobber at the same time and they will hit at the same time (minus any difference due to air resistance/drag associated with the size and not the mass) or drop a round ounce of gold vs a round ounce of tin of the same size (but considerably different mass) and they will hit at the same time.
Fella dropped two such items off the leaning tower of pisa many many years ago to prove this.
