Total newbie (to bolt precision rifles) question on bore cleaning. I run Otters bore cleaner on a patch, then a brass brush (.30 cal size), then wipe with a bore mop. If not shooting for a bit, run light oil. It's on a Bergara 300 PRC. Just ordered a Bore Tech Proof-Positive Bore Stix, coated one piece rod. Do I need to run a copper solvent? I'm not sure if copper fowling is an issue, or it's just another product for manufacturer's to sell. This may seem like a silly question, but I don't want to take any Joe Blow's youtube advice. TIA
