Air rifles were once considered accurate if they shot minute of soda can, but a lot has changed in the last 20 or so years. There are now air rifles capable of shooting pellets into one ragged hole at 50 yards and shooting .22 caliber projectiles at speeds greater than 1,000 fps. That puts air rifles in contention with the rimfires we use for small game hunting and precision shooting. 

To see how close airguns are to matching or overtaking rimfire performance, I compared data from our recent .22 rifle test and air rifle test. Both tests featured a wide range of budget to premium guns. I also did some head-to-head shooting of my own to collect more data. 

Modern Air Rifles

If the term “air rifle” conjures up images of a break-action or pump gun, you need to be brought up to speed on pre-charged pneumatic airguns. PCPs use a pressurized air cylinder or bottle to generate their power, which provides more accuracy, greater velocity, ease of use, and the ability to tune the rifle. PCP airguns also don’t require shooting techniques like the “artillery hold,” which is needed for spring-powered airguns. The trade off for all this performance is that a PCP needs some type of external air source, like a compressor or scuba tank, to fill the rifle’s air cylinder. Those compressors cost $500 plus dollars because they have to achieve more than 4,000 psi.

Accuracy

Both our air rifle test and our .22 LR rifle test used similar test protocols. For each test, multiple shooters squeezed off five-shot groups per gun, with a minimum of 20 shots recorded. It’s important to note that our .22 LR rifle test featured more rifles, more group shots, and a wider variety of ammo than our air rifle test. The .22 LR rifle test was done outdoors at 50 yards and the air rifle test was done indoors at 45 yards. So we don’t have a true apples-to-apples comparison, but the data provides an idea of what both platforms are capable of. 

At our airgun test, we shot three budget and three high-end PCPs. They averaged a .59-inch group average at 45 yards. The most accurate gun was the FX Impact, which shot a .41-inch group average. 

I selected three budget and three high-end .22 LR rifles to compare to our airgun results. Those six rifles averaged a .53-inch group at 50 yards with quality ammo. The best group average was shot by the MPA Matrix Pro with a .38-inch average.

I shot my CZ 455 (.22 LR) and my FX Impact M3 (.22 cal airgun) at 50 yards. The FX Impact’s five groups averaged .3 inches and the CZ 455 groups measured .35 inches. The big takeaway from that shooting session is that air rifles can absolutely compete, and, in some cases, beat a .22 LR at 50 yards and closer.

Things get more interesting at 100 yards, where the .22 LRs overall averaged .95-inches. At the air rifle test we shot the two most accurate guns (the Avenger and Impact M3) at 100 yards; those averaged 1.61 inches. You can dial in an air rifle to shoot sub-MOA at 100 yards with tuning and ammo selection, but it’s not as turnkey as a good .22 LR. One of the best examples is the Savage Mark II FV-SR ($309 MSRP), which shot a six-group average of .75 inches at 100 yards.

Ballistics 

Air rifles can shoot pellets or slugs. It’s often easier to achieve good accuracy with pellets because they shoot best at lower velocities. Slugs have a higher ballistic coefficient, a heavier weight, and must be shot at higher velocities to stabilize. They usually require a faster twist rate and a stiffer barrel since the higher power output affects barrel harmonics. The issue is that most air rifles come from the factory with barrels made for shooting pellets. So if you want to shoot a higher-BC projectile, you might have to swap parts. 

Still, a .22 LR blows any air rifle pellet or slug out of the water when it comes to ballistics. I put the above ammo into Hornady’s ballistic calculator to get an idea of how much of an advantage a .22 LR has over a .22 air rifle. The JSB pellet will get pushed 7.4 inches by a 5 mph crosswind at 100 yards and it will drop 21.4 inches from 25 to 100 yards. The ZAN slug will get pushed 3.5 inches by the 5 mph cross wind. The Lapua Center X would drift 1.7 inches, and only drop 8.3 inches from 25 to 100 yards. That .22 LR load will still be going 948 fps when it reaches the target. The ZAN slug drops nearly double that — 14.3 inches — and is moving at 753 fps. 

When it comes to terminal performance, I’ve found both PCPs and .22 LRs are highly effective on squirrels inside 50 yards. I’ve been amazed at how efficiently a round-nose pellet kills squirrels with both head and vital shot placements. I have no qualms about the ethics of shooting small game with pellets, and slugs only increase an airgun’s effectiveness. So if hunting is your main use for a .22, the air rifle and rimfire are both good options. 

What .22 LRs Do Best 

Beyond 50 yards, there’s no doubt that a .22 LR is going to shoot circles around a .22 air rifle. A rimfire will also deliver more energy for hunting because it shoots a heavier projectile at faster speeds. It can also shoot bullets at supersonic speeds, which an air rifle cannot. 

While a .22 LR has a longer dwell time than a centerfire rifle, which makes follow through critical, it’s still less than an air rifle. I have to concentrate on my follow through more on an air rifle than a .22 LR to shoot sub-.5-inch groups at 50 yards.

Ammo for a typical day of shooting, 200 rounds, takes up almost no space and is easy to take to the range. On the other hand, my FX Impact M3 gets about 60 shots per fill, which is plenty for hunting, but not nearly enough for a day at the range. If I want to shoot more than 60 shots, I’ll need to bring my portable compressor with me. 

A .22 LR usually has a 16- to 20-inch barrel, which is handy in the woods. Air rifles usually have longer barrels between 20 and 24 inches, which can make them more cumbersome to carry. 

What Air Rifles Do Best

A lot of people legally can shoot an air rifle in their backyard or basement with a simple pellet trap for a backstop. Fewer people can shoot a .22 LR at home. That convenience means more time shooting.

Air rifles are quieter than a suppressed .22 LR. I’ve shot them side-by-side and it’s a significant difference. Again, this setup makes for enjoyable backyard shooting and low-profile pest control. Another advantage for those circumstances is that an air rifle can easily be tuned down in power for close-range shooting. 

Air rifles come in a wide variety of designs from ultra-compact guns like the Umarex Notos to benchrest competition guns like the Karma Red Panda. Air rifles aren’t regulated like firearms so you can buy one with a short barrel without paperwork and, in most states, they can be shipped right to your door. The same goes for air rifle “moderators,” which work like a firearm suppressor to mitigate sound but don’t require a tax stamp. 

Ammo prices went up a few years ago and .22 ammo isn’t as cheap as it once was. A tin of .22 cal pellets will run you about $23 and about 4 cents per shot. Unless you find a good deal, .22 LR ammo is around 10 cents per round and really good stuff, like Lapua Center X, is about 30 cents per round.  

Air rifles are versatile. Rifles for small game hunting come in a variety of calibers from .177 to .30 caliber. The larger caliber rifles deliver more energy and can shoot higher B.C. projectiles. The smaller caliber options offer more shots per fill and are quieter. You can also get into the world of big bore air rifles for larger game.

The Upshot

Will your next .22 shoot pellets or burn powder? It all depends on what you’re looking to get out of it. Right now, a .22 LR is the easy button for small game hunting and precision shooting. There’s a wide assortment of quality .22 LR rifles available that will shoot well right out of the box. But if you can get past the learning curve and initial investment in an air source, an air rifle can open up more shooting and hunting opportunities.
