What cleaning method can help prevent excessive copper fouling?

Using a copper solvent after every shooting session is an effective cleaning method that helps prevent excessive copper fouling in a firearm's bore. Copper fouling occurs when bullets, especially those with a copper jacket, leave deposits of copper in the barrel as they are fired. These deposits can accumulate over time and negatively affect accuracy by inhibiting proper bullet seating and altering the barrel's interior surface.

By employing a copper solvent regularly, particularly after each shooting session, the shooter can dissolve and remove copper fouling before it has a chance to build up significantly. This proactive approach not only maintains the integrity and performance of the barrel but also ensures that the firearm continues to perform optimally over time.

The other options do not effectively mitigate copper fouling. Firing only high-velocity rounds may not significantly reduce copper buildup, and low-quality ammunition can actually exacerbate fouling problems due to poorer construction. Neglecting to clean the bore is counterproductive, as it allows fouling to accumulate, leading to decreased accuracy and potential damage to the firearm.
