Agree with Edward. You will need several cleaning rods to cover that wide of a range. Buy good cleaning rods. Buy one for 22-30 caliber, one for 32-40 caliber, and another for the big stuff. They need to be one piece, smooth, have industry-standard female threads for attaching jags and brushes, and have a good handle. Smooth metal, coated, or even graphite reinforced resin is good, that way they are easy to wipe off and won't scratch the bore of the rifle.
That said, there is no need for precision ball bearing swivel stainless steel iridium plated laser aligned diamond honed indestructible non-petrochemical polymer handle ground thread cleaning rods. I think some people confuse the fact that a cleaning rod is basically just a handle for the bore brush.
