I remove the barrel; I hold the action in my RH (I am LH) and with a finger gently move the bolt so that line is horizontal; when it gets in position, my left hand grips the charging handle and pulls. On one gun, it needs an ever so slight wiggle, on the other it comes out real easy (almost TOO easy). Once you get it out, let the bolt rotate forward and then slowly push it back so you can see just how far you need to go as you look into the spot where the handle goes. You will see the keyhole opening better that way.
