Get a Bore Tech coated rod, and a bore guide from Dewey. Dont for get to add 10 inches to the barrel length to account for the bore guide. They make cleaning rods up to 44 inches for 22 cal.
I have used Dewey rods, and like the Quality of the Bore Tech rods alot more.
If Brunos is out of them try Midsouth shooters 1-800-272-3000
