More info:
Attached is photo of my wall from inside the house. Wall here is cinder block and filled with concrete under the window. 5/8 sheet rock over 3/4 inch stryofoam, over 3/4 hat channels (airspace).The bullet did not exit to the outside. I still have discomfort in the ears, the level of my tinnitus is actually lower right now.
Attached also are some illustrations kindly provided by Butlersrangers. We have been calling the pivot in the sear a knuckle, which is fairly descriptive (SA calls it a hinge). What I have been calling first and final stage cams are referred to in the drawings as bearings and heel, not very descriptive to me. To me the sear is the actual area that slide past each other to release the trigger with the cocking piece having 1/2 as well as the surface on what Springfield Amory calls the sear. Maybe the definition has changed or I have been wrong all along.
Any comments on what we call these things will be taken into consideration.
The design of Krag trigger are normally trouble free and as mentioned by 2 members here, they have not had an accidental discharge with their Krags.
I hope the discussion helps all to remember safety. I can think moving through heavy brush one could possibly get twigs or debris in the trigger/trigger guard. We have at least 2 insects here that like to fill openings. The end of a barrel or the trigger guard opening would make a fine nesting spot for either one.
Again, comments, suggestions, and advice are welcome.
