I noticed that my ejection rod isn't 100% straight. Taurus Raging Bull 44Mag. I wondered if this could possibly affect accuracy. The rod is free flowing on the front-locked up on the rear. This lead me to mearsure cylinder to chamber gap. I have a consistant reading-which is good. However the reading is .0012, which seems excessive. Quite honestly, I don't know if it came from the factory like this or not. I know it hasn't been dropped or mishandled. Do I need to shim? Thanks Guys.
