CCI Copper-22: The Lead-Free .22 Explained

Light, fast and lead-free. Great where non-lead rules apply, and not what you want for plinking.

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.

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:

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.

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.
