Since I aquired a bore snake from COB when I purchased the .410 I really like using them and since have bought a snake for the 12 ga. as well.... It works pretty good on the 20. ga as well.... I also would like to get one for the other guns that I own... If I got one for the .22 would it be any good on the .243???? The next size would of been the .30 cal and I'm thinking it may be too big.... Any thoughts????
