I have a good friend that gave me his BLR to reload some ammo for. It is a 7mm-08 and about 20 years old. I gave it a good cleaning and took some measurements to determine the max COL. While handling it, I came across something that seems odd. Is it normal to be able to very slightly open the lever and still be able to pull the trigger dropping the hammer? Any info would be appreciated as I have zero experience with lever guns.
