the chamber on my .222 is as rough as a badgers arse....to put it mildly
some of my cases show the roughness in the brass
Now my "how hard can it be" mentality has me thinking a modified fire formed case on a extended power drill bit coated in some jewellers rouge would be a simple fix.
it is used for polishing glass and precious metals, surely must be able to remove some imperfections without removing too much metal or am I oversimplifying this?
thoughts before I get busy with the Bosch!
