at nearly mile, make up your frigging mind, cause you can't have it both ways. The 223 starts with 12x the power of the 22lr, and it loses its velocity a LOT more slowly than the blunt, soft .22lr bullet does. Ballistics charts show the 22lr, from a rifle, now, as being under 60 ft lbs remaining, at 150m. That's the Military's figure for minimum power to still be lethal, ie, the same as a .25 ACP at the muzzle. You can look at the RATE of velocity loss of the .22lr, and see it will have atmost 40 ft lbs left at 200m, at most 25 ft lbs at 250 m, and at most 15 ft lbs at 300m. In other words, it will hit at MOST like a pellet rifle does, at 300m.that's from a RIFLE, too. The .22 pistol starts with considearbly less power at the muzzle.

At 400m, you can turn your back on .22 lr pistolfire, and cover the back of your neck with your hands, wear a thick jacket, and let ******* shoot at you all day with .22 pistols. If they EVER manage to hit you, it will feel like somebody TOSSED the bullets at you. :)

Start an 80 gr Berger vld at 2800 fps, from a 24" barrel, however, and take a look at its rate of loss of velocity. It starts with 1400 ft lbs, and it's still got 600 ft lbs left at 600 yds. Once a boattaied spitzer goes subsonic, it loses its velocity at a very slow rate, indeed. 80 grs at 1050 fps is still 200 ft lbs, ya know.
