Get a one piece cleaning rod with either a screw on jag or a made on jag. If you get a made on jag you'll have to live with it, as is, but that's not so bad. Get another rod for brushing - same rod except threaded to screw in the brush. Buy as long a rod as you think you can stand. Never settle for one just long enough if you can help it. Some rods are expensive and some not so expensive. Some are good and some are not as good. Get a couple of one piece rods and glue up some PVC pipe for a rod holder. Be sure to leave the ends long enough and unglued so you can clean the tubes. Put a screw there or something...to keep the end caps on. Oh yeah, buy a rimfire rod!
Others will need to tell you where to get a bore guide but buy that first. You really need a bore guide that fits well and will come out when it gets hot!!! If others fail....I'll make some calls.
