Not really new to hunting or shooting, but not a "gun expert" either. I allowed my 7mmRemMag (factory model 700, not custom) to go about a year (maybe 10 rounds fired) without cleaning the bore. The other day I ran a rag through it and upon inspecting it with naked eye and pointing bore toward lamp, noticed that it did not come completely clean. I have yet to run a brush through it or try any other remedy. I'm hoping/assuming I havent done any permanent damage - what are your thoughts? Can some of you more technically sound shooters give me the "for dummies" version of cleaning a rifle bore - I've been taught different things over the years? Keep in mind I'm not a competitive shooter - just a recreational mid-range hunter. thanks in advance for your input, and I apologize if this thread is better suited for a different forum; I wasn't sure.
