Ok one thing I now know that I did wrong was that I didn't allow the brush to spin in the bore. I held onto the rod when I pushed it some not the handle which spins. I was told the brush should spin with the rifling. However, since I didn't allow that am I going to risk any damage?

I was told by a gunsmith not to use brushes but it seemed like it got soo much more stuff out than not using one.

I'm hoping I didn't damage anything. I may just go back to not using them.
