The .223 is about as potent at 100 yards as the .222 is at the muzzle.
Someone is under estimating the 222...
Really? Care to back that up?
Here are ballistics for Winchester's factory loads:
.222, 50 gr.
Muzzle 100 200 300
3140 2602 2123 1700 feet per second
1094 752 500 321 foot-pounds
.223, 55 gr.
Muzzle 100 200 300
3240 2871 2531 2215 feet per second
1282 1006 782 599 foot-pounds
Now, please explain for me how I am underestimating the .222 when I say that the 1006 ft. lbs of energy of the .223 at 100 yards is about as potent as the 1094 ft. lbs of energy of the .222 at the muzzle. Keep in mind that a generally accepted rule of thumb for deer rifles is that they have a minimum of 1000 ft. lbs of energy at impact.
Sounds to me like the biased opinion of someone trying to justify his purchase of a .222...
