Stop cleaning it. Putting oil in the bore after every few rounds isn’t helping anything.
Exactly what I was thinking. I have 3 Rugers including a 6.5 CM in a M77 Hawkeye varmint/target. I have never used more than 15 or 20 rounds to break in a barrel and usually clean after 4 or 5 rounds during the break-in process. I have several older rifles that I never broke-in and they shoot just as accurately as those that I did. Personally, not even sure if break-in is necessary especially for a hunting rifle. I typically don't clean my rifle barrels until accuracy starts to drop off, unless I'm working up a new load.
