Cleaning a used CZ 452 Ultra Lux 28 inch that I recently acquired off Gunbroker, leaves score marks on my Pro-Shot .22 thirty-six inch cleaning rod. It almost feels like the rod is not true, but I can't really eyeball down it's length accurately due to the fixed handle. You can feel the score marks on the rod. a piece of 220 grit paper will take them back out, but, I'd really like to know what is amiss. Seems to me there must be a burr or nick somewhere along the bore, no??? What should I do? Use a .17 cal rod? Otherwise the gun seems to be a one hole shooter based on one outing so far! Anyone else experience something similar?
Thanks in advance!

VtMacDoc, some Questions/comments that came to mind:
1) Burrs were mentioned. Regardless of cleaning rod brand, do you use a bore guide that could keep rod centered and straight down the bore?
2) I could ask more questions about cleaning process; however, do use a wet patch before using a bore brush? I am reserving some questions but may want to know if you use patches and what do you do when the patch exits the barrel on first pass out the end of the barrel.
3) Regardless of patch or brush passes, does the rod "feel" any rough spots? IF so, when?
4) If you use patches, do you use very tight patches making passes hard to push down the barrel?
5) Also, maybe not too important to you right now but I know the Pro-Shot name regarding rod attachments. I do not have a Pro-Shot rod but I have to be careful the diameter of patch jag (metal) for different calibers. From my Lazy-Boy chair, I can't tell what causes marks on your rod. I will not bill you for my comments. I said that because I gave some trap shooting tips to a lady surgeon and I told her that there is "no charge". I told her that she needed help and she smiled but also laughed at my comments.
Let me know if I can cause more confusion but I was looking for more input. More data was needed, I think. Don't worry when my sarcasm or my sense of humor sneaks out.
How does that Ultra Lux shoot and group when the operator works okay?
DeltaGray off Subject for now but don't send a big net to catch me.

This is a fairly common occurrence on CZ rimfire rifles. The bolt guide, item #34 in the illustration in the manual, is what is making the marks.
Some shooters use a 17, or 20 cal, rod. Some remove the bolt guide, and some use a pull through system for cleaning.

painter, thanks for the post. I don't own any CZ rim fire or center fire rifles but like to use bore guides.

If I use a rod, I also like to use a rod guide. The problem is the bolt guide will push the guide off center.
Without getting into a long drawn out discussion of rimfire cleaning techniques, I just use a pull through for the bore, and occaisionally a brush and solvent to clean any carbon in the chamber/leade.

Thanks Folks!

Ok, Ronnie,I have different tips and diameters that fits Dewey (spelling or (SP ?)) rods. I found a shorter Dewey rod yesterday that I used in Thompson Contender barrels. At least my longer rifle bench rest rod rotates in my rifles.
I use different brand/caliber related bore guides and the only problem I had more an operator problem--using a patch size that was too large relative to the tip that I used and/or barrel nominal bore diameter. I use different threaded rod tips for different calibers.
This may be more than you wanted to read but I can think faster than I can type while I watch TV as I am doing my touch typing (not look at keyboard). I used to be an introvert.
DeltaGray --Over and Out for now, except that I have not slugged a P-09 9mm barrel to see what sized cast lead I may use some day in it. That piece is training on jacketed projectiles and doing great!
