On Colts I may after 30-40 rounds I will wipe the cylinder face and put a drop of oil on the cylinder pin/cylinder/frame juncture every 30 or so rounds. Same for my Euroarms Remingtons.
On my Uberti Remingtons shooting full loads (30 grs+wad+ball+grease) after two cylinders fired I put a single drop of oil (olive or Ballistol) on the front of the cylinder where it rubs on the frame. About 5 seconds of holding the gun up and twirling the cylinder works it down onto the cylinder pin. I do this AFTER recharging the chambers. The guns will shoot all day.
With over 15 perCUSSIN' revolvers, I've been called the Imelda Marcos of cap & ball.
