" The bore looks shiny, but could the rust have changed something?"
My guess would be that even though the bore looks shiny, the rust slightly roughened the bore surface. The result of that would be more friction, and increased pressure for the load you've been using.
You might try working DOWN from that load in small increments. When you reach pressure similar to what you were getting pre rust, it may group better.
Clearly, the rifle needs to be cleaned more often than your friend is doing.
