.44 magnum muzzle energy: 1650ft·lbs
.223 muzzle energy: 1300ft·lbs
Actual values may vary depending on barrel length and bullet weight, but the .223 is a rifle round with less muzzle energy than a large caliber pistol.
In comparison, the .308 Winchester muzzle energy is about 2700ft·lbs, and the .338 Lapua Magnum approaches 5000ft·lbs (again depending on bullet weight, powder load, and barrel length). For extreme sports enthusiasts, the Barrett M82 chambered in .50 Caliber BMG (800 grain) has a muzzle energy over 14,000ft·lbs.
Thanks, I know.
I have shot guns encompassing all of those calibers and am familiar with ballistics.
What I am tired of is if a talking head says that a .50 BMG is a mouse caliber there are FReepers who have never shot a gun that would parrot what the idiot MSM says and argue with FReepers who have been actively shooting for 50 years.
That is what bothers me and this isn’t pointed at you.
Let’s be generous: A 240 gr projectile coming out of a 7.5 in barrel @ 1500 fps has 5 Ft-Lb per grain resulting in 1200 Ft-Lb on my calculator. That being a VERY hot load.
I see the point you are trying to make. The 55 gr 3100 fps .223 REM muzzle energy is 1250 Ft-Lb, making the muzzle energy of both about the same.
I think the media attached “high power” to an article where a crossbow was mentioned. It’s just too hard to resist using that zinger to keep the sheeple wetting themselves into voting our rights away.
