Why do all my other doubles open fully for loading and extracting and the two mentioned do not? It's too cumbersome to be normal. It's too smooth to be caused by obstruction or mechanical. An adjustment of some kind?
King,
Your LC should be fully cocked before the end of the barrel opening swing cycle, you can feel the hammers cock and the sears set. Cocking should go over center and the sears set at about 85%-90% through the opening cycle, not at the absolute very end.
Most likely the cocking plate in your forearm needs adjusting to cock properly, the screw is on the top of your forearm facing forward at an angle. It is item #56 in the upper left corner with the forend iron group, and is available from Numrich by phone or on line for $3.00 USD + shipping. A new cocking plate screw is also available, item #57. The cocking plate is also pictured for your review.
Adjustment is very simple, but if worn you need a new one. On the other end of the cocking rods you have the hammers #26 and #27 and the cocking cams #17 and #18, it is unlikely they are worn, as they are hardened steel.
Best Regards,
