I too have used Hoppes for 40 plus years. I used to soak my revolver overnight in a glass jar full of Hoppes to loosen the lead fouling in the barrel, between the barrel cone and receiver top and front of cylinder. Worked wonders! But, it wasn’t copper fouling? I’ll try several things according to you and the other experts here. Other than that, I’ll just shoot it as often as I can. But, I’m also considering switching to Barnes for my Browning.338 , replacing the Remington Core Lokts which have now become more expensive than the Barnes cartridges! Go figure?I’ve used Hoppe’s #9 for 65 years. I’m addicted to the smell.
I have found in my rifles that Barnes bullets shoot tighter groups once the bore is fouled well. I do clean it well occasionally. First Hoppe’s soaked for 15 minutes or so. A few patches. Then Hoppe’s again. While wet, a bronze bore brush 10 strokes each direction. Then patches until they come out clean (usually 5-6).
My rifles are mostly stainless steel Tikkas, Kimbers, and MRC. There barrels were polished from the factories supposedly.
