My question is, how can the crown matter that much??? *Most* of my guns have muzzle devises on them, when I remove said muzzle device those pretty crowns are always covered in thick, irregular carbon. My groups are the same with a freshly cleaned crown and with a crown that is crusted up with carbon......
Yes I am at work and things are s l o w.
Keef:
All the crown does is protect the bore from damage. Some believe that certain angles of the crown assist in accuracy but there isn't much evidence to back them.
So, carbon on the crown probably won't do anything. If you decided to take a triangular file and file a notch in the bore, I bet your accuracy would drop.
