I am enjoying reading the conversation that is occurring on this thread. Good open dialogue is the best way to develop solutions to problems.

But, it is important to understand that if you drop a ton of lead or an ounce of lead from the same height at the same time, both will hit the ground at the same time.

If you shoot a round horizontal to the plane of the earth at 3000 fps and drop a round at the muzzle the same time the driven round leaves the muzzle, both will hit the ground at the same time. This is gravity.

Tungsten shot kills 15 yards further for a given shot size because of sectional density of the shot. I shoot little shotgun, but assuming both lead shot and tungsten shot is fired at the same intial velocity, the tungsten based shot with its superior SD will always kill at longer ranges in proportion to the difference in the SD.
