Decided to deep clean my rifle tonight.
Brass brush, tight patch, saturated in 40x
20 passes per patch of 40x
Use an oiled patch after each 20 passes for 10 passes
After 4 bore cleaner patches they were coming out the color of the 40x and the red oil i was using.
This is all after 40 brush/patch passes 3 weeks ago with #9.
Really impressed, certainly wont use it every time but im amazed how different my crown and barrel looks.
