Hi Everyone,

So I took out the new .22LR with Horseman2, who is a wonderfully generous man BTW, and it shot awesome. First time ever shooting a .22LR and only I think my 3rd time shooting any gun ever. It shot a really nice group of 5 after sighting in of about .24 inches @ 50m. That's with a 3-9 x 40mm. I could be measuring it wrong.

So needless to say I'm in love with this thing. It's an awesome first rifle. I want to clean it right. I don't want to damage the rifling etc.

I have a dewey rod in .17 with a .22 jag. I read up on using a bore rod guide and bought the Dewey .22 model, but it doesn't fit rimfires. I read about not coming out the end of the muzzle, but I can't find a bore rod guide, so what should I do in this case?

Just be gentle?

Thanks a million!
 
Next time we meet you can try one of my CZ bore guides.
Your measurement of a .24 c-c is probably pretty close as it appeared to be less than .5 o-o.
That VXII is pretty handy for your gun and if you decide to keep it as your basic scope/rifle combo, changing the parallax might be the ticket.
The parallax on my 4-12 Rifleman has been changed to 75 yards but with a .24 who would suggest making changes?

Just ordered one of those bore guides for my CZ American any tips.. the guns shoots great at 50meters so now taking it.. to 100M and it`s looking good
 
There is no need to clean the bore unless accuracy drops off. Cleaning the bore frequently may even be counterproductive, as many .22s need to be fouled to shoot their best.

Exactly. I cleaned my cz barrel after it had been sitting for about a year and took 75 rounds before it was shooting like it should again. Shot some eley team as well and took almost 50 rounds before it was shooting in the .3" at 50 yards.
 
I use nylon brushes on my .22LR firearms to brush out the "chunkies" (powder fouling residue) and minimize wear on the bore.

A popular phrase used is "bore seasoning", firing fouling ammunition (of the same type) after cleaning before the barrel accuracy stabilizes.

Best rods out there if you ask me. I ordered a 36" long 22LR 0.187" rod from here: http://www.ivyrods.com/CleaningRODS.htm

As for bore guides, not sure if Mike is still making these or not. I have one from him, but that was a few years back. Specified that I had a 0.187" rod so make sure it was sized properly for it. http://www.6mmbr.com/catalog/item/1433308/954882.htm

These guys are still around for sure, though. I have one of these bore guides for my Anschutz 1712, and would feel quite comfortable getting one of theirs for my CZ if I didn't yet have one. Again, specify 0.187" rod will be used so they can size it properly. http://www.mwerksllc.com/cz.php

Both my CZ 453 Varmint and my Anschutz 1712 are more accurate when clean, and just 25 shots to get bullet lube through the length of the barrel. And they are cleaned after each day out. Accuracy doesn't fall off horrendously or anything if I don't clean them all the time. But when shooting for score, they're cleaned and get the 25-shot warm-up before a scoring shot is fired. :) Your mileage may vary.

edit - btw, you might consider altering your ejector to keep it from harming your rods. I've done this to my CZ 453 Varmint and my old Brno Model 5, too. Didn't affect ejector function at all. I had one rod scratched like crazy before thinking about doing this, heh.

After. You can see I took a little of that corner off.

Before. You can see the ejector sticking out into the boreline around 7 or 8 o'clock:

After. You can't see it in the boreline at all now:

Thanks for the info Shorty. I did one quick clean when it was new as I was recommended to do so to get out all that factory cosmoline. My rod got scratched up in several places so your suggestion is most appreciated.
 
For 22s, and also for patching centerfires, I'm a huge fan of the patchworm. Google it, it's essentially a plastic string with a nub on the end. Pierce a patch on the string down to the nub, feed the string through the breach until it comes out the muzzle, and pull the patch through from the muzzle end. Ez pz, and no worry about rods damaging the barrel.

I'm no expert on 22 accuracy, but what I do for cleaning my 10/22's barrel is simply some Hoppes 9 patches and then dry patches with the patchworm. For my centerfires I use a bore guide with dewey rod to scrub with nylon brushes, but use the same patchworm for all patching.
