Not 100% but pretty close. They are also much cleaner than shooting standard lead bullets. If you have a rough bore, the thin copper coat can be scrapped off and you will still get some leading.Do copper flashed 22 caliber bullets prevent lead fouling in pistols?
Have you ever used the lubed 22’s? They were messy to handle. Canuc used to make them. I don’t like cleaning lead fouling.Not 100% but pretty close.

Were they CCI Clean22? How was the accuracy?You might want to try the polymer coated 22’s. I bought a box of them from Walmart. Used them in revolvers didn’t see any leading in throat or barrel.
Most un-plated .22 bullets are lubricated with wax, some more than others.
Plated bullets are usually used with high-velocity rounds to reduce fouling and those too are often waxed.
.22 rimfire fouling is typically quite soft and easily removed, IF it ever becomes an issue. A far greater problem is powder fouling in the action, which DOES need to be removed regularly.
I have some .22 LR guns with thousands of rounds between bore cleaning after shooting a mix of bullet types and they're fine. What's wrong with your gun that you are having so much concern about bullet fouling?
Similar to you, I used to load thousands of 9mm poly-coated as well as 225g for cheap plinking 300 Blk subs. Very clean shooting.Just as an FYI. I’ve been using polyner coated bullets in my reloads for 38 spl, 45 acp, 32 S&w, and others for years with no barrel leading. All low power loads.
I shot wad cutters in a revolver aI’d say it minimizes fouling.
All my ammo is copper jacketed or “washed.”
I shot some lead wad cutters in my .38 revolver.
Once.
I will look them up!You might want to try the polymer coated 22’s. I bought a box of them from Walmart. Used them in revolvers didn’t see any leading in throat or barrel.
