Galileo’s famous 1589 experiment at the Leaning Tower of Pisa, in which he dropped two different spheres of different mass and observed that they reached the ground at the same time, tells us something about modern ballistics – it tells us that both a large bullet and a small bullet, when shot from the same location at the same target, will drop at the same rate and hit the ground at the same time.
This means for one bullet to have greater range it must travel faster, and increased velocity results from either a stronger propellant or reduced mass. For two rifle cartridges that have the same amount of gunpowder, the cartridge with the lighter bullet will always have the greater range.
While a heavier projectile should be expected to inflict more damage on a target, at the end of the day “dead is dead”. In fact, an opponent who is wounded by a smaller bullet may very well still be taken out of the conflict while at the same time requiring time and attention from their comrades that might otherwise be spent attacking you!
When it comes to prevailing in the “two way shooting range”, bigger is certainly not always better.
Our book, “When There is No FEMA – Survival for Normal People in (Very) Abnormal Times” provides detailed information on the use of guns for home and community defense, including the proper selection of guns based on specific needs.
