Is there a rule of thumb as to the final pp diameter of the bullet in relation to actual bore diameter?
Just like shooting lead, you'll want to slug your bore and get an actual measurement. Generally, the lead bullet in a paper patch is just at or just over the land measurement and the patch is sized to about .001-.002 over the groove measurement.
