As part of ONR's electromagnetic railgun program, the stored energy, launcher and terminal area will be increased in size to accommodate a MJ muzzle energy
gun by fiscal year 2009.
While the Makarov is more powerful that its closest relative, the .380 Browning (9x17mm or 9mm Short), it generates significantly less muzzle energy
than either the 9mm Parabellum or the .45 ACP (Figure 10).
The .410 achieves its respectable muzzle energy
via a high velocity.
hollowpoint at full velocity of 1,150 fps, the .38-40 generates 468 foot-pounds of muzzle energy
. A 155-gr.
Original .35 Rem factory loads launched 200-grain bullets at about 2,050 fps and therefore produced about 25 percent more muzzle energy
than .30-30 loads.
I have received more than one panicked telephone call from a national parks investigator about to go into court asking me to calculate the muzzle energy
on, say, a .303 for the purposes of his testimony when the chain of evidence in a poaching case was starting to unravel for one reason or another and an alternate charge was needed.
it was the most powerful production smallbore air rifle generally available It produces 65 foot-pounds of muzzle energy
in .22 cal.
Firing the gun at that muzzle energy
level will require an even greater input of energy into the system itself, says Zowarka.
If desired, you can enter projectile weight and the LabRadar will calculate actual muzzle energy
in ft-lbs out as far as you instruct it to.
of muzzle energy
while the 6.5 PRC produces 2,782 ft.-lbs., but at 400 yards the 6.5 PRC closes that gap.
While the rifle lacks the muzzle energy
and optic mounting system specified by the colonel, it meets the overall length (OAL) and feeding requirements.
The common bullet energy formula for foot pounds of muzzle energy
is bullet weight in grains multiplied by muzzle velocity squared, divided by 450,240.
