Out of a 14.5" I get 350 ish yards.

carrying right around 400 foot pounds of energy.

While the .22 mag only has 315 at the muzzle.

I hope your not trying to run around telling people "herp a derp, 5.56 ain't much better then .22 mag"

Spitzer bullet vs round nose. 45 maybe 50 grain max for .22mag vs all the different heavies for 5.56.

edit. Did the math wrong.

Go to hornady's ballistic chart-it's all there.

Still carrying just over 1k energy.

Are you saying that at 350 yards a 55gr 556 load is still carrying over a 1000 ft/lbs or energy?

looks like they are close @ 225yds... 22WM 909ft\[email protected], 55grn vmax is about 904ft\lbs @ 1000yds and 45gn is about 890ft\lbs@1000

Not sure where you are going with this ?

Yes it will, if you start with a 4500fps muzzle velocity.

55gr bullet with a 3000fps MV has almost exactly 400 ft. lbs. at 350 yards.

Oh crap, I must have entered it wrong into bulletflight. Yep. Y'all are right I get 401 at 350.

Funny though the fps calc was still right.

KE. ME is KE at the Muzzle. Hence the whole "Muzzle Energy" name versus "Kinetic Energy."

Aside from the energy, remember that the .224" bullet is substantially longer, which will cut a wider path.

The energy doesn't mean much when you get past frag level velocities.  Having shot several deer at 400-450 yards with 75 gr OTM they still do some significant damage. Wether from tumbling or bulket deformation I don't know as I never recovered one.  22 Win Mag will easily kill deer and hogs Inside 100 yards witha good broadside shot if that is what you are wondering.

Safer to say can kill rather than will easily kill I think. Using rimfire for deer hunting is illegal in many states.

Anybody know about 5.56 out of a 7.5" barrel?

The legality of it has no effect on it's ability to do so.

I think he's making a point about relative quickness. An expanding .270 in the same spot is likely  to result in a much faster kill. But I think we're pretty much all on the same page here.

reason for the question, 22 Magnum is pretty devastating at short ranges, impressively so.

22 WMR  bullet 50 grains at 1,750 feet per second.
