This is my first post, so go easy on me. I put it in gunsmithing instead of equipment as I am looking for a more technical answer rather than opinion. I have been shooting for 30 years or more, but have recently taken it up a notch with my new Remington 700 P in .308. How do barrels get scratched from cleaning rods? Assuming you use a bore guide and care it doesn't seem logical. Aluminum and brass are softer than a barrel, according to Pro-Shot my stainless one piece is as well: "Thank you for your email, I will address you question. *First, the cleaning rod is made from 416HT steel that has an (Rockwell Hardness) HRC of 26, it is a different steel totally than the barrel steel. *Barrel Steel is made from 416R. *Barrel steel is much stronger and tougher than our rod material. *Not to mention we also centerles grind, micro polish, and finish polish the rod to a finish of 6. *Regular machined stainless steel has a finish of over 30. **If you have any additional questions or concerns, please let me know." Thoughts on SS cleaning rods would be welcome as well. So, how do cleaning rods scratch barrels?
