Whatever you decide on....don't do this.I could never understand how a much softer aluminum cleaning rod can bugger rifling if a copper bullet doesn't. I use a bore snake with a bit of Hoppes soaked rag in the finger loop. Drop the weighted end through the bore, step on it, raise rifle and pull through as I guide the finger loop and rag end to chamber, continue pulling through by stepping ahead on cord as needed till completely drawn through the bore. The rag provides enough compression to thoroughly clean the bore.
I use the same Sinclair one with the o-ring that tjones mentioned.
