CCI Copper-22 is one of the more unusual .22 LR loads on the shelf. Instead of a lead bullet, it uses a very light, lead-free bullet made from a copper-based composite. The listing shows 21 grains, roughly half the weight of a standard 40-grain .22 LR bullet. That design produces a load that behaves differently from normal rimfire ammunition, with real advantages and real limits. This guide explains both, so you know when Copper-22 is the right choice and when it's the wrong one.
This is a buyer's guide based on manufacturer information and ballistic principles, not a range test. Check CCI's current published specs on the box or listing.
| Bullet | 21gr lead-free copper-based composite HP, per listing |
|---|---|
| Velocity | Much faster than standard 40gr .22 LR, because of the light bullet |
| Why buy | Lead-free requirements, reduced lead exposure, fast-expanding small-game bullet |
| Watch for | Accuracy varies by barrel; different point of impact than 40gr |
| Box | 50 rounds, per listing |
| Rule | Zero with it before you hunt with it |
Why lead-free .22 exists
Some jurisdictions require non-lead ammunition for hunting. California is the best-known example. Some ranges, and some shooters, simply prefer to cut lead exposure, especially shooting indoors or with kids around. Lead-free rimfire ammunition used to be scarce. Copper-22 was one of the first widely distributed options, which is why it still shows up in so many hunting-regulation conversations. Always check your own state's current rules before a hunt.
What the light bullet changes
A lighter bullet leaves the muzzle much faster than a standard .22 LR bullet. That has three practical effects:
- Flatter over short ranges. Within typical small-game distances it drops less, which can make holds simpler.
- Different point of impact. Expect it to hit somewhere different from your usual 40-grain load. Re-zero or record the offset, as covered in our rimfire zeroing guide.
- Wind sensitivity. Light bullets shed speed quickly and can drift more at distance than you would expect from the muzzle velocity. Our rimfire wind guide explains why.
Twist rate and accuracy
Most .22 LR barrels use a twist rate chosen for 36- to 40-grain lead bullets. A very light composite bullet may shoot well in one barrel and poorly in another. That's a normal result of how twist rate and bullet design interact, not a defect. Read our rimfire twist rate guide for the background. The practical answer is to shoot a group before you commit to a hunting plan.
Does it cycle semi-autos?
The high velocity generally helps semi-autos cycle, but every action has its own tolerances. Test a few magazines in your specific rifle or pistol. If you have feeding problems, check our semi-auto jam troubleshooting guide before blaming the load.
Copper-22 vs a standard lead hollow point
| CCI Copper-22 | Standard 36-40gr lead HP | |
|---|---|---|
| Lead-free | Yes | No |
| Bullet weight | 21gr (listed) | 36-40gr |
| Velocity | Higher | Standard or high velocity |
| Point of impact | Different; re-zero | Your usual zero |
| Best use | Lead-restricted hunting, low-lead shooting | General small game and plinking |
Good uses and bad uses
Good: squirrels, rabbits and pests where non-lead ammunition is required; shooters reducing lead exposure; carrying one fast-expanding load for close small game.
Poor: bulk plinking, because it costs more per round than bulk lead; precision rimfire competition, where standard-velocity match loads are more consistent (see our competition guide); and long-range rimfire, where the light bullet's rapid speed loss is a disadvantage.
If you shoot suppressed, note that a supersonic load produces a crack no matter how good your suppressor is. Our suppressed .22 guide covers that trade-off.
CCI Copper-22 is a specialist load: lead-free, light and fast, and very useful where non-lead rules apply. Zero with it, check that your barrel groups it, and keep bulk lead ammunition for plinking.
FAQ
Is CCI Copper-22 legal for hunting in California?
California requires non-lead ammunition for hunting, and Copper-22 is lead-free. Always check current state regulations before hunting.
Will Copper-22 hit where my regular .22 hits?
Usually not. The much lighter bullet flies differently. Re-zero or record the offset before hunting.
Is Copper-22 accurate?
It depends on your barrel. Light composite bullets shoot well in some twist rates and poorly in others. Test groups first.
Is it good for suppressed shooting?
It's a supersonic load, so it produces a crack even when suppressed. Use a subsonic load for the quietest shooting.
