Proving once more that unintended consequences of “gun control” actually increase dangerous crime, The Detroit News reported Thursday that “Guns are being stolen from vehicles downtown, in part because nightclubs and the NFL ban firearms.”

Unable to bring their firearms into venues that ban them, many gun owners are nonetheless unwilling to travel to and from such locations without the means of defense, and are opting to have their firearms with them as long as they legally can, then storing them in their cars.

So instead of allowing gun owners to bring them into the stadium to keep them safe, they’re requiring that gun owners turn them over to criminals.  They’re doing this for the children.  Consider the children …

Apparently believing that the American public had not yet been subjected to enough ridiculous fearmongering over the supposed “undetectability” of firearms printed from plastic, ABC’s Katie Couric ran a short segment on her show, “Katie,” last week, titled, perhaps not surprisingly, “The Dark Side of 3D Printers.”

Who is Katie Couric?

Here is the NSSF on smart gun technology.  I said before that Daily Caller annoys me, and increasingly so.  Notice that NSSF doesn’t have any prima facie objections to smart guns, but they point out that they might be unreliable.

Pfft!  I object to smart guns because they’re unreliable too.  But I also prima facie object to smart guns because of government interference and potential usage in gun confiscation or registration shenanigans.

Uncle links this post on revolver science, entitled why heavy, slow bullets hit higher than light, fast bullets.  Okay, since the original author starts the science lesson, I’ll finish it.  He’s dealing with the gun and bullet as a system rather than individually, considering the affects of recoil on the trajectory.

But rather than titling the post about heavy bullets, he should have stayed on point about the overall system.  It isn’t an enigma why heavy bullets and light bullets have the same drop given the same velocity, or another way of saying it is that he should have left out the discussion of heavy and light altogether and stuck with velocity and the affects of recoil on the pivot point of the firearm.

If you take a bullet of 180 grains and one of 230 grains, and hold them the same height and drop them, they will land at the same time due to the acceleration of gravity, which is the same and constant regardless of mass.  Alternatively, drop a marble and bowling ball from the third floor of the stairwell of your college physics building, and they’ll land at the same time (remove people from the stairwell before attempting this experiment).

Of course, I’m leaving out a complex discussion of aerodynamic drag, from which I could explain why it’s better for folks with trucks like my F150 to leave the tail gate up instead of down, but I’ll save this for another lesson.

This is why BDC is a function of muzzle velocity (and aerodynamics for such rounds as hollow points), but not bullet mass.  Okay, is that clear to everyone?  This is basic physics, and everyone should understand this, especially shooters.  If you have to adjust BDC for your rounds given different bullet masses, it’s because of different muzzle velocity due to mass (and because lower velocity rounds won’t go as far), not because heavy objects drop faster than light objects.  Heavy bullets do not drop faster than light bullets.  Finally, in order to get an idea how quickly your bullet is hitting the ground, hold it at the height of the gun you’re shooting, drop it, and time it.  When it hits the ground, it would have hit the ground if you had shot the bullet out of the barrel of your gun, just some hundreds of yards away.
