NEVER clean the BARREL of a precision rifle!
This experiment challenges the necessity of deep cleaning precision rifle barrels, suggesting it may not improve accuracy and could even be detrimental if not followed by a fouling shot. Testing a Savage 10 Tactical in .308 Win, the rifle maintained sub-MOA groups with a dirty barrel. Mild cleaning showed no significant change, while deep cleaning resulted in slightly wider groups, potentially due to heat and lack of fouling.
