Lead-Free .22 LR: Where CCI Copper-22 Actually Fits

Most shooters never need lead-free rimfire. The ones who do usually have a specific rule or a specific worry behind it. Start there and the choice gets simple.

Start with the reason, not the bullet

Lead-free rimfire ammunition is easy to over-think. The product itself is simple: a bullet made of something other than lead. What varies is why you are buying it, and the reason decides almost everything else, from how many rounds you need to how carefully you should test it.

Here are the four situations where it comes up.

When it is a hunting rule

Some jurisdictions require non-lead ammunition for hunting. California is the best-known example. Others apply restrictions by area, species or type of land. These rules change, and they vary in ways that a general article cannot track. Treat anything here as an example, not a map.

What to do:

• Read your state wildlife agency's current regulations for the season you intend to hunt, in the area you intend to hunt.
• Confirm whether the rule covers rimfire and small game specifically, because some rules are written around big game or specific species.
• Keep the ammunition box or a note of the load with you, in case you are asked.

On the practical side, Copper-22 is a light, fast, fast-expanding bullet intended for small game at modest distances. Our small-game hunting guide covers shot placement and range limits that apply with any .22 load, lead-free or not.

When it is a range or property rule

Range policies vary widely. Many ranges care far more about steel-core or tracer ammunition than about lead. Some restrict lead for environmental reasons, particularly where the land drains into sensitive habitat. A few indoor facilities prefer non-lead to ease ventilation concerns.

Do not guess. Call or read the range rules and ask what the actual wording covers. If the rule is about the bullet, a lead-free bullet satisfies it. If the rule is about the whole cartridge, check the primer.

When it is about your own exposure

Shooting produces lead exposure from more than the bullet: the primer compound, fouling and dust all contribute. Switching only the bullet addresses one of those sources.

If lead exposure is your concern, the honest questions are:

• Does the manufacturer describe the primer as lead-free too, or only the bullet?
• Are you shooting indoors with poor ventilation?
• Are you washing hands before eating and handling cleaning gear carefully?

Lead-free ammunition is one tool, not a complete answer. Good ventilation and hygiene matter at least as much.

What a 21-grain bullet changes in your gun

Per the listing, CCI Copper-22 uses a 21-grain lead-free hollow point, about half the weight of the traditional 40-grain .22 LR bullet. That difference has consequences.

A different point of impact. A lighter bullet leaves the muzzle faster and drops differently. Do not expect it to hit where your usual 40-grain load does. Re-zero or keep a record of the offset. Our rimfire zeroing guide explains how.

Wind sensitivity. Light bullets can lose speed quickly. At longer distances, they may drift more than their muzzle velocity suggests. See reading wind at rimfire distances.

Twist-rate interaction. Most .22 LR barrels use a twist rate chosen for standard-weight lead bullets. A very light composite bullet may stabilize and group well in one barrel and poorly in another, and that variation is normal. The twist rate article explains the background.

Cycling. High-velocity loads generally help blowback semi-autos, but the only way to know is to try a few magazines. If feeding problems appear, go through the jam checklist before concluding the ammunition is at fault.

Matching the load to the job

For squirrels, rabbits and similar pests where lead is restricted: a fast-expanding lead-free hollow point is what the category is designed for. Shoot a group in your rifle at the distance you will actually hunt.

For paper and cans: there is little reason to use lead-free unless a rule requires it. Plated bulk ammunition is simpler and more economical.

For indoor ranges that ask for it: use it, but check that the load is accepted and compatible with their backstop.

For suppressed shooting: light, fast bullets like this are typically supersonic, so a suppressor will not hide the crack. Subsonic loads are the quiet choice. See the subsonic comparison.

How to try it without overbuying

Lead-free .22 comes in small boxes, and the listing is a 50-round pack. That is exactly the right size for an experiment.

1. Buy one box.
2. Fire a handful of rounds to confirm it feeds and fires in your gun.
3. Shoot two or three five-shot groups at the distance you care about.
4. Compare with your regular load and note the point-of-impact difference.
5. Decide, and only then buy more.

If you want to see how it stacks up against conventional plated loads, browse the .22 LR ammo category for comparison. For a conventional hollow point to measure it against, the Browning BPR guide and the Aguila options in our Aguila lineup comparison are the usual reference points.

The short list

• Buy it if a rule requires non-lead ammunition, a range asks for it, or reducing lead handling matters to you.
• Skip it if you simply want cheap plinking ammunition. A bulk plated load will do that job better.
• Always shoot a group before you hunt with it, and check current regulations before every season.
