Hello and welcome back to another edition of The Rimfire Report! In this ongoing series, we cover everything from some of the oldest examples of rimfire guns and ammo up to the latest releases that we’ve seen at places like SHOT Show 2025 and more. A few weeks ago we took a look at CCI’s Clean-22 Steel Challenge 40 grain ammunition. To sum that article up briefly, the ammo performed exceptionally well in the consistency and cleanliness departments. When it came to accuracy, however, I found the CCI Clean to be lacking and as I mentioned a few weeks ago – this is probably because the ammo isn’t intended to be a precise target ammunition. To further demonstrate this, I took my remaining CCI Clean-22 40gr out to the range along with my freshly cleaned SIG Sauer P322 COMP pistol, to see how well the ammo does out of a more practical Steel Challenge gun.
