Lilja Group Buy Barrel Accuracy

[montana]

When I started my Lilja barrel break in, "as they recommend" I had a lot of copper fouling. As I continued cleaning after every shot the copper fouling became less and less. I had one particular land and groove that held the copper fouling longer than the others until around the 9th shot and cleaning. I could see this land and groove fouling on my cleaning patches. This could have been a very small rough spot that retained copper which could effect accuracy.
I would try their barrel break in method and see if this has a positive effect on your accuracy.
