Like Dusty said....if a trigger/action is timed so that it has some cock on close, the cocking piece does not come back far enough to pick up the trigger unless the bolt is pulled back a bit, after the handle is at the top of its travel. Try that, and if it cocks every time, then you know what your problem is, and it is not the trigger. If you are bothered by the cock on close, the cocking piece can be modified, but that needs to be done by someone with the equipment and machinery to do it precisely, so that the correct geometry is maintained, and the correct amount of metal is removed without taking too much off. BTW cock on close is pretty common, and is generally not a functional problem, since actual operation of the action, loading and unloading, requires cycling the bolt back and forth, which solves the problem as far as picking up the trigger is concerned.
