She got a sister??I doubt that it will ever get sold. I wish I could up load the group I shot a 100 yards today with it but its to large of a file. 3 bullets all touching. CZ 452 with pentax 3X9 and CCI HP ammo. The best thing? My Girlfriend bought it for me!!!!!!!
Well, first of all, it is a CZ, so it has a tight bore. DO NOT fool around trying to use a regular .22 rod in it. If you must clean it, get a good one piece coated rod, Dewey make a good one, in 17 caliber or 20 caliber. Get a good bore guide and use it, Possum Hollow #92 from Brownell's, among others. And yes, absolutely clean from the breech end. You should never need to use a brush, just a few wet patches and dry patch until clean and dry. And you dont need to do that very often.Well what tears it up from cleaning? The rods I use are brass. Is it best to clean from the back end of the gun after I remove the bolt?
I bought a Remingtom 40-X target rifle from a school team that shut down (same reasons). I calculate that it has a minimum of 200,000 rounds through it, and probably twice that.I have seen match rifles with hundreds of thousands and some possibly MILLIONS of rounds through them that still shot incredibly well. These were from high school rifle teams that were done away with when guns somehow became evil in the last few decades.
I have a Volquartsen barrel on my 10-22 and the "approved" way to clean it is to hang a patch on a piece of lawn trimmer line and gently pull the patch thru the barrel - no rods-no brushes. The guys at rimfire central (a great .22 info site) say that it may take 100 or so rounds to get a good 22 barrel "back to accurate" after even a gentle cleaning.Well what tears it up from cleaning?

Keith. Maybe your chamber was cut improperly, or the barrel was not set back far enough??... After about 5000 rounds, the bullets are not slightly engraved anymore, in fact I can not see land marks at all.
You are probably more knowledgeable than I. But, for what it is worth, someone who shot competitively told me to never use copper coated bullets, only lubricated lead bullets. He said to shoot the gun until accuracy falls off, then clean. It will take a few (?) rounds to coat the barrel with lube and fouling to get it back up to its original accuracy.and the does errode the throat. I built a ruger 10- 22 with a Rem 40x barrel installed on it with a match reamer that very slightly engraved the bullet as it was chambered. After about 5000 rounds, the bullets are not slightly engraved anymore, in fact I can not see land marks at all. It will still put 10 shots of Green Tag in the same hole at 75 yards, but obviously there is some wear going on. I really abused the gun in N. Ca and N. Nevada shooting ground squirrels.
The biggest thing that destorys accuracy in a rim fire is copper/lead fouling from bullet speeds in excess of 1250 fps. All of the plated bullets deposit some lead and copper fouling in the barrel and on the super accurate target rifles, you start to see accuracy drop off after 250 rounds.
Having said that, I clean my 40x barrel ever so often, when I feel like it. I think that a major factor is that the powder fouling can attract moisture.
