How heavy is the copper indication on your patch? I'm assuming your rifle has the sporter barrel, your groups look pretty good for a light barrel. How many rounds down the pipe? The bore may need a bit more break in and you may need to use a carbon remover along with copper remover. Bore Tech Eliminator copper remover and carbon remover works extremely well in my 204 Ruger. Interesting, your grouping changes for the better with 10 in/lbs difference from the last test. Cleaning every 10 rounds will help to cool your barrel down.
