All Rods are not the same Diameter and neither are the Jags . You also have to optimize the shape , material , and size of the Patch ( I like Proshot Patches )with the particular Jag you are using .... I have not tried any of the new Triangular Patches which are not supposed to stick yet , but will probably order some . Anyway , my old Dewey Rods work fine for 22 and larger , not so fine for 20 and 17 .....they Kink ! I like the Tipton for the small Calibers , but as mentioned in previous Posts ( they can blow apart and stick you ) so I'm going to use some sort of thick glove ....just in case . I also like the Bore Tech and Kleen Bore Rods , and have heard the Ivy is the Rolls Royce of Rods , but have never seen one . I can't remember but I think the Ivy is Spring Steel . If I were starting from scratch , I guess I would just follow Butches advice .
