I bought a pre-64 Winchester Model 70 in .220 Swift from a friend a couple of years ago. The rifle is like new and I know my friend took excellent care of it. The 26" barrel is stainless steel. The first time I took it to the range I checked the bore to be sure it was clean and it appeared to be bright and clean. But, just to be sure I gave it a good scrubbing. No matter what I do it seems impossible to get a clean patch even after 15 or 20 scrubbings with several bore cleaners, a tight brass bore brush and many cotton patches. I've been cleaning guns my whole life and never had this occur. Am I missing something or is the stainless barrel just hard to clean. I have fired only 100 rounds through the barrel using my reloads that are not "hot" in .220 swift terms. I was shooting 50 grain bullets at about 3,500 F/S.
Any suggestions?
