When I was assigned to write this article, my initial thought was probably the same as your own. "22 LR vs. 223 Rem? It's a little strange to compare a rimfire to a centerfire cartridge, isn't it?"

But the more I thought about it, the more sense it made. The two rounds do share the same bullet diameter. You can fire either in a 5.56 AR-15 with minimal modification. They're both intensely popular. Yet despite these similarities, the two rounds have very different applications, ballistic performance, and stopping power.

The 22 LR and 223 Rem have little recoil, making them excellent options for beginners who are learning proper shooting mechanics, as well as advanced shooters honing their craft. However, there is a drastic difference in recoil between the rimfire and centerfire cartridges.

Recoil is an important consideration when purchasing a new firearm (and cartridge). A round with heavy recoil is more difficult to control, and slows the rate of accurate follow-up shots.

Felt recoil is subjective. It varies from shooter to shooter, which is why we determine a cartridge's actual recoil by measuring its free recoil energy. It is determined by four factors: muzzle velocity, propellant charge weight, bullet weight, and firearm weight.

When fired from a 6 pound rifle at 1,255 fps muzzle velocity, a 40 grain 22 LR bullet generates ~0.19 ft-lbs of recoil energy. When a 62 grain 223 Rem bullet is fired from an 8 pound rifle at 3,025 fps muzzle velocity, it generates about 4 ft-lbs.

Despite this apparent large disparity, no one would argue that 223 Rem has high recoil. Anything under 15 ft-lbs is pretty manageable to most shooters. As one of the weakest cartridges, the 22 LR's recoil looks extremely low compared to pretty much anything.

Trajectory

The little 22 LR cartridge's bullet trajectory is satisfactorily flat over the short range it is intended for. The larger 223 Rem's trajectory is flatter to any distance, however, and makes long-range shots possible that the 22 LR cannot.

"Trajectory" describes a bullet's flight path over a given distance. Shooters can measure trajectory in inches of bullet drop, milliradians (MIL), and minute of angle (MOA). I used inches of drop in the following examples.

A flat-shooting cartridge is generally preferred for long-distance shooting because it requires fewer adjustments to compensate for bullet drop. It is also more forgiving of ranging mistakes.

The 22 LR is not a long-range cartridge. When zeroed at 50 yards, a 40 grain 22 LR bullet leaving the muzzle at 1,235 fps velocity will drop -5.8" at 100 yards, -45.0" at 200 yards, and a whopping -129.8" at 300 yards.

Here is a bullet drop chart to give you a general idea of the 22 LR's trajectory.

Note: The above chart shows the performance of one 22 LR load. Actual ballistic performance varies depending on bullet weight, lot number, barrel length, and environmental conditions.

When zeroed at the same range, a 40 grain 223 Rem bullet leaving the muzzle at 3,650 fps will rise 0.7" at 100 yards, drop -0.7" at 200 yards, and drop a mere -7.1" at 300 yards. Unsurprisingly, the 223 Remington has a much flatter trajectory than the 22 LR, making it the better choice for longer-range shooting.

Accuracy

Accuracy is subjective; the sum of too many variables to calculate. The primary factor is the shooter, who cannot be measured completely. The firearm, the ammunition, and the environment also factor heavily into just how accurately one cartridge can perform.

Within 50 yards, the 22 LR and 223 Rem share similar accuracy. Firing the 22 LR beyond that range can prove very difficult for novice shooters. Conversely, few novices encounter any difficulty shooting past 50 yards the first time they pick up a 223 Rem rifle.

Even though the shooter experiences more recoil from the 223 Rem, it's rarely enough to affect their accuracy. The 223 Rem is the more accurate cartridge, generally speaking.

Once again, the 22 LR is outclassed by the larger cartridge. Despite firing projectiles of virtually identical diameter and potentially identical weight, the 22 LR cannot match the 223 Rem's kinetic energy.

A 42 grain 22 LR bullet leaving the barrel at 1,320 fps generates 162 ft-lbs of muzzle energy, and conserves 103 ft-lbs at 100 yards. A 38 grain 223 Rem bullet leaving the barrel at 3,800 fps generates 1,218 ft-lbs of muzzle energy, and conserves 814 ft-lbs at 100 yards. At 300 yards, the 38 grain 223 bullet conserves more energy (340 ft-lbs) than the 42 grain 22 LR bullet has at the muzzle (163 ft-lbs).

Hunting

The weaker 22 LR is limited to small game hunting. I love using it for squirrels and rabbits, but it often lacks the stopping power needed for an ethical kill on anything larger.

The 223 Rem is considered too powerful for small game, but excels at varmint hunting. I keep a 223 Rem rifle nearby for any coyotes that roam through my pasture.

The 223 Rem can certainly take down a whitetail with proper shot placement and within the appropriate range, although many states have deemed it too weak for that purpose and banned it on ethical grounds.

Home Defense

I'm not a fan of using a rifle for home defense. Rifle cartridges are more likely to overpenetrate than pistol cartridges or shotgun shells. However, when comparing only these two cartridges for defense, I'm grabbing my 223 Rem every time. It's more reliable (as centerfire primers generally are, compared to rimfire ones), and has greater stopping power than the 22 LR.

Ammo & Rifle Cost/Availability

22 LR rifles and ammo are less expensive than 223 Rem rifles and ammo. Both cartridges are extremely popular, and readily available (except during times of extreme shortage).

Parting Shots: 22 LR vs. 223 Remington

Both cartridges are excellent choices for learning proper shooting mechanics and form. While both fire .22 caliber bullets, they differ in many ways, making one or the other a better choice depending on the circumstances. The 223 Remington is the better choice in nearly every instance. The few scenarios the 22 LR is better for are plinking (as it is less expensive), small game hunting, and teaching recoil-sensitive shooters how to handle firearms.

No matter which you choose, Ammo.com has dozens of options for both cartridges with great prices, fast shipping, and excellent customer service!
