Would you also recommend not cleaning when switching between powder/bullet combos when during load development?

Haven’t seen the need with normal bullets.

I agree with Form. More rifles are damaged from cleaning than from shooting to many rounds. Factory barrels definitely seem to shoot better once they have some rounds down the tube.

Use a dedicated copper cleaner. I like boretech products. Also it looks like your cleaning jag is brass. Get a coated jag.
I’m not sure how accomplished you are as a reloaded and you may be very experienced, but your load development as described by you could be your problem. You describe varying your powder charge which is a good first step. This is called ladders for those of us that do load development. What I did not hear you say is where you chronograph the loads to see what charge yields the most consistent shot to shot velocity. This is important to identify in shooting through your ladder progression. You should also identify accuracy nodes in the ladder that should have better groups.
Once you find an acceptable and low velocity deviation ladder within an accuracy node, you need to go one step further. You need to find the accuracy nodes associated with seating depth. In order to do this right, you should measure your chamber and determine what is your max COAL. Hornady make a good tool to measure your lands. Next step is to find a jump accuracy node by varying the depth you seat the bullets. I start this at the point the ogive touches the lands. Then seat test round at .020 deep progressions until you find your jump accuracy node.
I am with most everyone else. I doubt copper fouling is the problem. Most likely your barrel doesn’t like the bullet powder combo you are experimenting with.
If ladders and accuracy nodes are new to you, I suggest spending time on the reloaded and shooting forums on the web and study up. I spent many weeks developing an accurate load for my cooper backcountry 280 ai this summer. I had 5 range sessions before I found the perfect combo of powder, charge, bullet, and seating depth. It was worth the trouble. My cooper shoots .25 inch 5 hot groups at 100 yards all day long.
