Was going to pull the trigger, so to speak, on a 5" 625-8 last night, until I noticed a small area of discolorationg on the cylinder (and the DA pull was too heavy).
It was a 2-3mm dot between lightening cuts, with a bronze hue, no dimpling. Looks as if a drop of a caustic substance dripped on it.
Salesman told me that it may be where they proof tested the cylinder. I could imagine a a brass gauge held against the cylinder wall to test for expansion as a proof load was fired leaving such a mark.
Then again this could be total BS.
