You guys need to stop comparing 357 magnum pistol velocities to 223 rifle velocities:
From my 375 magnum chambered, 20 inch barrel, model 92 clone, a 125 grain Sierra Hollow Cavity can be pushed at 2,350 fps. That develops 1,533 foot pounds of muzzle energy.
My wife's little 16 inch barreled AR in 5.56mm, pushes a 52 grain Sierra hollow point at 2,950 fps.
That load produces 1,005 foot pounds of muzzle energy.
My 16 inch trapper chambered in 357 mag, will only push the 125 grain load to 2,175 fps.
It develops 1,313 foot pounds of mathematical muzzle energy.
Even if I load up my 20 inch heavy barreled 5.56mm AR to 3,000 fps using a 60 grain Sierra HP ( a good coyote load for winter) , I still only end up with 1,200 foot pounds of muzzle energy.
About the same energy as a 357 caliber 158gr Speer jacketed soft point, being pushed at 1,800 fps from my model 92 clone.
Out at 100 or 150 yards they swap due to the poor ballistic coefficient of the 357 bullets. But that does not matter at 15 feet inside your house. Or even 50 yards .
