Got new 452 Yesterday. Today I'm still getting patches that come out brown. Wow, they must have really put some preservative in the bore at the factory? Just ran some Butch's BoreShine thru it. Gonna let it sit and run more patches later.
Might get rings tomorrow :P

The color you're seeing is bluing salts.
Shoot it. ;)

Thanks, I'll run a dry patch thru and put scope on this weekend and shoot it about 25 rounds and then clean it again.

You're supposed to clean these things??

I've heard extensively on other forums that with the CZ rimfires, an initial THOROUGH cleaning
is recommended and then probably not again unless it begins to shoot poorly with the same
ammunition, however that is just the opinion of a brand new CZ owner so take that for what
its worth which might buy a cup of coffee at McD's these days.

I did run a couple of patches down the barrel on mine when I bought it. That was ten years ago. I wipe down the outside and the bolt but other than that, nothing. It still shoots lights out.

Initial thorough cleaning is needed to get the factory preservatives out. After that i pull boresnake trough every few hundred rounds. Or oiled patch and few dry patches every few thousand rounds. Never before the match as it takes a few magazines to condition/season the bore again. Main area to clean is the chamber, extractor and lube the bolt lightly.

I have one 453(22lr), 2 452'(22lr and 17hmr), and a 455 with one 22lr and 17hmr barrel and I initially cleaned them to get the "brown goo" out. In cleaning the bore it may take multiple patches and in others just a few, but once you get the "brown goo" out, just starting shooting the rifle. At this point sight in the rifle at 50 yards, buy several brands of ammo, CCI, GECO, SK, Lapua, Federal, Remington, etc to determine which brand your rifle likes.Your rifle will let you know which brand will give you the best groups. After all this, have tons of fun with your particular shooting type, blinking, shooting holes in paper, bench rest, 4 position. But the bottom line is this, the rifle wants to be shot, so have the aforementioned fun and enjoy the addiction of owning a CZ rifle. I predict this will not be the only one you own.

This is an interesting topic, as there is such a wide spectrum of cleaning "regimens" out there. On the one hand, quite a few shooters I've talked to feel that .22's are different from centerfires, and that the bores never need to be cleaned. I suppose the middle grounds involve various frequencies of running a boresnake down the barrel every now and then. On the OCD end, I imagine some shooters treat rimfire the same way as centerfire rifles, cleaning them before, after and during shooting, with solvents, patches and brass brushes.
I'm not sure there is any "right" answer, but it would be interesting to know what seems to work best for accuracy.
