I just picked up my first k98 and am concerned about the bore condition. I have run brake cleaner, CLP, Hoppes thru it with a brush (my cleaning rod broke after 6 or so passes thru so I had to stop with the brush)and several patches and it doesn't look like it's improving too much. Does this bore appear to be beyond saving? I need to make a decision whether to return it or not and look for something else. Thanks for any help.
