Ken, I may be mistaken but the action you describe sounds quite similar to the magnum research "Lone Eagle" single shot pistol. They have a screw in breach and a seperate cocking lever that has to be worked to fire it.
<br>I agree they are a pain to load but they sure put - um where you point.
<br>I`m under the impression that some artillery uses a interuped thread, screw type breach also.
