KenL: I too saw some very minor burrs on my Beartooth cva
I took some fine grade valve lapping compound a patch wrapped
around my wire brush. About 50-100 strokes and the burrs were
gone, and the inside of the barrel looked like a mirror. I think
this also helps with accuracy. I realize that different gun makers
use different processes to make their barrels. I just thought it
odd that the so-called-cheap ML would have lands & grooves so
much more pronounced than some of the higher-priced ones.
Thanks for your comments.
