I'm glad we are ironing things out here, here is something from the Chuck Hawks web site:
The .223 Remington has become our most popular varmint cartridge, and one of the best selling of all rifle cartridges. It has been adopted for military use by nations all over the world. Military style .223 ammunition is widely distributed and very inexpensive. Unfortunately, it seldom delivers the gilt-edged accuracy demanded by varmint hunters.
Some .223 Remington factory loads, however, are extremely accurate, considerably better than military ammunition. One of these is the Remington factory load with the 55 grain Power-Lokt bullet. This is a hollow point spitzer bullet designed specifically for varmint shooting. It has been reported that this bullet will usually group into .5 to .75 inches at 100 yards from a .223 varmint rifle. Most handloaders would be hard pressed to load more accurate ammunition.
Current factory loads drive a 55 grain bullet at 3,240 fps at the muzzle. Muzzle energy is 1,282 ft. lbs. The figures for the Remington 55 grain HP Power-Lokt bullet at 200 yards are 2,352 fps and 675 ft. lbs.
Factory trajectory tables show that a scope sighted .223 shooting the 55 grain spitzer bullet and zeroed at 200 yards hits 1.5" high at 100 yards, 1.5" high at 150 yards, 0 at 200 yards, 3" low at 250 yards, and 7.9" low at 300 yards. The .223 is a 235+ yard varmint cartridge.
Most serious varmint hunters with .223 varmint rifles will handload the cartridge for maximum accuracy and performance. The most common bullet weights run from 40 to 60 grains, with the 50-55 grain bullets being the most popular for varmint hunting. Widely recommended powders include H322, H335, BL-C2, W748, Benchmark, and IMR 3031. Here are some specifications .223 reloaders should keep in mind: bullet diameter .224", maximum COL 2.26", maximum case length 1.76", MAP 52,000 cup.
The fifth edition of the Nosler Reloading Manual shows that 24.5 grains of Benchmark powder gave the Nosler 50 grain Ballistic Tip bullet a MV of 3285 fps, and 26.5 grains of the same powder drove that bullet to a MV of 3540 fps.
23.0 grains of H335 powder behind the 55 grain Nosler bullets produced a MV of 2920 fps, and 25.0 grains of H335, the most accurate powder tested with that bullet weight, gave a MV of 3140 fps. These Nosler loads were developed in Winchester cases using Remington 7 1/2 primers, and were chronographed in a 24" rifle barrel.
I have found that in my Savage Model 12 Low Profile varmint rifle, the 60 grain Hornady SP bullet in front of 22.8 grains of IMR 3031 powder delivers top accuracy. This is a maximum load. The MV of this load is given as 3000 fps using Winchester cases and WSR primers.
Remember that the .223 Remington is a varmint cartridge. Despite its success as a military cartridge (where it produces "casualties"--not necessarily quick kills), it is not a big game cartridge and should not be used for hunting deer and antelope. Shooting a 55 grain bullet, its optimum game weight is only about 19 pounds at 200 yards.Note: A full length article about the .223 Remington can be found on the Rifle Cartridge Page.
