W-48 Training Rifle dark rings

[bucnball]

Bought a Polish Mosin 22 cal rifle yesterday. Got it home & bore-snaked it to find 2 dark rings in the bore about 5 inches apart. What caused them ? Apology for no pics as I learn by rote & I can't find anyone to show me .Thanks !

Might be lead. Hard to say without seeing it. If it's a rough place sometimes you can smooth it with some lapping compound.

I found a post on the Smith & Wesson forum about a similar thing.  Does it look like this?

Not quite as rough  as the picture but there are two dark rings that are down the bore from the muzzle . I probably should take it to the range before the day gets too hot & see what sort of 5 shot groups @ 25 /50 yds it makes w/cci standards.. It may not need much remediation (I hope). Thanks again !

It's a .22 built like a tank.  Go shoot it.

There are some cleaners on the market that will remove them if they are lead, which is most proable.

Clean the bore good and see if that helps. Heavy duty 22lr rifles.

Sounds good to me .. I've got some bronze wool & a one- piece small bore cleaning rod w/a few attachments including a cotton bore mop , a slotted tip & a patch pusher . Also have some valve-lapping compound . What lead removers do TGO'rs recommend ?

[DWARREN123]

Any of the ones sold for firearms seem to work well plus there is info on the internet on how to make a DC powered one which seems to be a extra heavy duty cleaning tool.

Bajabuc and I cleaned the bore of the rifle & when the patch on the tip passed the the dark rings the cleaning patch zipped across the the spaces w/o any resistance.. We felt along the barrel to see if there were any discernible bulges but couldn't find any.. Lacking a bore scope we figured the rifling was gone in a  couple of places & wondered if it would be worth re-lining the bore.. I've got less than $250 invested in the rifle so far. A new sleeve would cost about that (plus shipping) . It still shoots, but not as accurately  as I would like . What do you suggest? (I don't want to sell or trade anything that isn't in good shape, a feller gets a bad reputation & life's too short to worry, etc.) Any ideas ? THANKS !

Needed $$$ for car repair so I sold the rifle as-is to a collector  @ my cost. He was pleased to get it and values it as a C&R item. I'm glad I could sell it & appreciate the interest of TGO members .THANKS !
