I read somewhere that it is suggested to use a smaller rod like .20 or .17 but suspect that is because of the ejector is in the way.
What does everyone use for a bore guide to clean CZ 457 22lr?
Do you remove ejector and if not, how does your guide clear it?
I suppose it may just be easier use a bore snake.
 
Just to say, there's lots of threads about cleaning 22LRs, and the 457s especially need attention to keep accuracy. Many competition shooters clean every 100-ish rounds or LESS to keep accuracy consistent. Then again, there are some people who just shoot 'pop cans' and bore-snake or whatever every year or two. Choose your style . . .
I have a 457 VMTR and a 455 Lux, both with ca 2500 rounds and I clean every time I go out, sometimes only 40-50 rounds. If I get around 100 or so, I'll clean at the range at that point, too. And I just shoot for fun . . . it's just NOT FUN to shoot 1" groups !!
 
Well,
I have a CZ 457 inch n an MDT XRs chassis.
I have never “cleaned” it.
It shoots amazingly well.
I have never and wud never shoot anything but lead match bullets in it.

No copper and none of that “copper washed” garbage.

I have come to believe that is key.

Works for me anyway.

I dont shoot “pop cans” lol
I shoot steel at 300 yards regularly tho.

Bugholes at 50.

Do what works for u.

Tight bore on those. Use a 20cal jag if you can find one. If not, wrap your patches around a clean bronze brush.

Or, what I do, is use an Otis pull through.

No. Its because CZ .22 bores are actually tighter, and thats why they're a lot more accurate than your average U.S. built. Unless all of my 452s and 455s have extractors half way down the barrel of course because that's where things get tight. Just as tight coming back to the chamber so the extractor thought is not valid. Hammer a. 22 brush down the barrel if you are so inclined or just use a .20 non coated rod and jags and eliminate any chance to do some damage.

And anyone using a bore snake vs a proper cleaning rod is nuts. Fine for removing debris after a day wracking gophers down south but next to no value for a proper cleaning. Use one in a CZ 452/455 and there's a good chance the next cleaning tip will be firing a couple of rounds down the barrel to remove the material left behind when the string broke.

OP, buy yourself the proper rod, brushes, and jags. They're lovely little rifles and deserve extra care and attention. Not offshore or US slop. I suspect most recommending otherwise don't even own CZ .22s.
 
Lots of good advice about buying quality rods, bore guides and premium brushes and being gentle/careful/precise when cleaning your rifles.
BUT…as per Anschutz an Olympic level air rifle or Olympic level .22LR should never ever see a bore brush…even once !!
The bores are diamond lapped to a mirror finish and with their air rifles felt pellets only are used to clean the bores. They never see a brush or rod. The .22LRs have braided Dacron 50lb string pull through with cotton patches only. The bore snakes are a no no because the have bristles imbedded in their weave. Air rifle field target shooters with expensive PCP rifles also use pull throughs exclusively. No brushes… and solvents that’s won’t damage the ‘O’ rings within.
With rimfires it’s important to use quality ammo without jumping around different brands because accuracy needs a consistent combination of lead alloy and bullet lubricant within that tube. Some of us ‘overclean’ and do more damage than good. Unless I think I might have moisture in the barrel due to weather conditions I’ll let 2,000 rounds go through before I pull 3 or 4 patches to clean the bore out to relatively bare metal. A good quality rimfire will still produce impressive results on paper or pests even after a half dozen bricks of ammo go through it. The old Bruno rifles and all the CZs have great barrels and should be treated the same as match rifles when their barrels are cleaned.
They too are diamond lapped so it’s not surprising that they shoot so well. Cheers
 
I use a pull through bore snake on my cz 457 Lux .17hmr. Anything more I would worry about possibly damaging their insanely accurate beauty.
 
The bores are indeed tight, but I still had to file the corner off the ejectors on my Brno Model 5 (basically the same as the CZ 452) and CZ 453 Varmint to stop them from scratching up my polished stainless 0.187" Ivy rods. Both were high enough to be in the boreline.
 
Thanks for all the advice. Really appreciated!
I ended up getting a 17 rod and adapter. 22 jags fit and the biggest issue I had was the bore guide. Purchased a Possom Hollow bore guide cut specifically for the CZ 457 and could not be happier.
Fits like a glove with a cutout. So much so that you need to use the bolt release putting it in and out.
