Works for me

[Minihuntur]

Yesterday I sighted in my .243 (If I wouldnt have choked on the last shot the group would have been less than 3/4 in.) and after running a dozen rounds or so out of it I clean it. But I was out of bore solvent so I tried the best all-around solvent/penetrant/lubricant I knew of... WD-40. I took the bolt out and put a cleaning patch in the throat of the bore and tilted the muzzle up slightly. I sprayed WD-40 down the muzzle and waited about a minute. Then I put some cardboard down to catch the drips and pushed the patch through the bore. It worked great, it cleaned twice as well as the other stuff. Also to save money on patches, I buy cheap, disposable jaycloths and cut them to fit the different calibers of my guns.
