One of the Newtonian principles is that of the mass : velocity equilibrium (if I may call it that). Simply explained in gun terms, it’s that compromise that one has to make between bullet weight and velocity (and eventually, terminal velocity and impact).
The simplest example is a comparison between a .22 bullet and .45-70 Government: the first zips along with a muzzle velocity in excess of 3,000 feet per second, while (relatively speaking) the huge .45-70 struggles to leave the barrel altogether. Yet as fast as the .22 may be, its diminutive 40gr weight arrives without much authority, so to speak, at (say) 100 yards distance, while the .45-70’s 300gr lump of lead will crush everything in its path when it eventually gets there.
Which is all very well and good, because the difference between the two bullets is vast.
But what if there’s little difference in bullet weight between two (or three) bullets, the only difference being the amount of powder driving them?
Here’s a fun video of just such a test, made by shooting the .22 LR, .22 Mag (WMR), and the .17 Hornady Magnum. (By the way, I love the fact that Our Hero eschews the appallingly-expensive ballistic gelatin, using instead large cubes of pottery clay to make his point. It’s as valid a medium as any other, I think, when making comparisons of this sort.) Go ahead and watch the thing (it’s just over 10 minutes long), and then come back here for my thoughts.
