After being horrified after using my Teslong for the first time, I assiduously cleaned my barrel with a different copper and/or carbon cleaner with different brands each night. The barrel was as clean as I can do it. I shot yesterday. I took two foulers (as always) and then proceeded to shoot three shot groups at 100 yards. The first four targets looked like a 20 gauge spread. Then, it settled down into 1/3 MOA on a 10 mph swirling wind. I was using CFE 223. Sam load, depth, brass, bullet etc.
Should I let some copper build up on the lands? Carbon? Keep cleaning assiduously?
