Copper fouling and accuracy

[Smoak352]

12 rounds? After you clean with copper solvent do your groups open for a few shots?

When done for the day I run oiled patch twice and clean patch when ready to shoot. Sometimes I snake it out when I forget rod.

Yes, The first few shots don't usually group that well. Most people put a fouler shot or two down the barrel before shooting groups or going hunting.

It's good to know what your cold bore shot is along with clean bore. Just in case.

What does this mean exactly??

I don't clean for copper after barrel break in. Once broken in, I only use M Pro 7.

Kelly McMillan told me to never clean for copper unless it is excessive.

Todd Hodnett has said he never cleans for copper either. He took a 1/4 MOA gun and cleaned all the copper fouling. It turned into a 2 1/2 MOA gun. 45 shots later.....it settled back into a 1/4 MOA gun with no copper cleaning. It's in the Magpul video.

Cold bore -first shot is different in most cases
