Here is my issue, New MRC rifle, stainless X3. Did my normal break in process and cleaning procedure I have been doing for 20+ plus years and after the 5th shot and cleaning my bore became jet black. Does not appears to be etched.
My process is as follows:
75/25 ratio of Kroil/hoppes Patch and nylon bore brush until clean
Sweets 7 a few patch and until no more blue is noticed
Finish with one patch of Shooters choice FP10
Never had this happen before
any help or suggestions would be appreicated
Thank you in advance
