I just broke in a Lilja barrel on my .243 AI using Butch's Bore Shine. Standard procedure used... series of one shot/clean, etc. After shooting four 5-shot groups out of it last week, I cleaned the barrel before I left the range. First patch with Butch's had powder residue and light traces of copper. Second wet patch had only a small amount of residue and nearly no blue. Dry patch. One more wet patch, nothing. Dried the bore and went home.
When you get results like this, (and this isn't the first gun this has worked this way for me with this) you gotta have the faith.
Sorry to have gotten off the subject, but I did want to pass my experiences along, for what it's worth...........
