Putting a new Bergara ML barrel on my Encore. The pin fits the frame just fine = close, no slop and is good and no problems on the other barrels. The bergara barrel pin hole is so tight the pin will not go through. It will start for about 1/8" each side and then gets really tight and cannot be pushed or easy tapped through. I am NOT going to drive the pin in! Wondering how to best polish the pin hole on the Bergara lug. Get some fine "garnet" paper and slowly polish hole and frequently try pin or what? Insight and anecdotes welcome. Thanks, 10
