when i buy a used rifle, one of the first things i do is a proper bore cleaning. you would be suprised at how dirty some can be! many gunsmithing books will tell you to start with a proper bore cleaning in the search for accuracy problems.
Several years ago, a good friend bought me his Sako 7MM Remington magnum to sell at a gun show.
I knew he loved this rifle, so I asked why he wanted to sell it. He told me the bore was shot out.
I took the rifle to my workbench, and looked through it with a bore light. It looked almost like a smooth bore.
I cleaned it with Sweet's 7.62 several times. when it looked clean, I used the Outer's Foul Out to get the last traces of copper out.
I brought the rifle back to Ralph, and asked him to shot it before deciding to sell.
A couple of weeks later, he called me, very excited, and told me that the Sako shot better groups that it had when it was new.
No way would he sell it.
I asked him how he cleaned the bore. He said that his father had taught him that with modern ammo there was no need to clean the bore.
I took Ralph to the LGS and got him to buy a large bottle of Sweet's, a steel one piece cleaning rod and an Outer's Foul Out.
10 years later, his beloved 7mm Sako still shoots 3/4 MOA.
