Just got my Browning o/u out of the cabinet to check and clean it for the first time since last season and the ejectors operated taking the tips off the clear plastic snap caps. i spent an hour with a small screwdriver breaking them out. It has been caused by the Youngs "303" oil i swabbed the bores with last year before storing the gun... worth a check for sure. If i had arrived at our first outside day it would have been embarrasing to say the least. Brass or alloy from now on and i reckon that is why all the top gunmakers issue nickel or gold plated?
