I'm cleaning a set from an old M&H. The brass is so soft that even the slightest pressure has the tool digging deeply into the metal. Is burrs can easily be carved off with an Exact knife, it's so soft. I'd like to just replace them but the threads mic' at .280" (9/32). Stuck between a rock and a soft place...
