Background Info: At the Illinois State Championship match in Milan Illinois last weekend, on our first stage, my wife's Stoeger Coachgun single trigger 12ga opened on its own after her first shot (right barrel). I purchased this shotgun new on 2023-06-24. After her ST opened up on her, she used my Stoeger Coachgun Supreme double trigger for the rest of the match. I was videoing when it happened, and I've included a frame showing the dang thing opening on her. When it was new, I installed a “Palo Verde Stoeger Top Lever Spring” from Long Hunter. It's adjustable by spacer selection. I chose the least tension without there being any slop in the top lever. It's been working fine that way for a year, but now, out of the blue, it has started opening on its own. My Cowboy load recipe is 7/8 oz #8 shot, 10.7g of Hodgdon Clays, Federal 209A primers. I took it to my local range and shot some Bornaghi 7/8 oz SubSound shells and it opened on its own after the first shot every time. Then I added spacers to the Palo Verde top lever spring to make it the highest spring tension possible. Then went to the range again. The first test was the SubSounds and it failed (opened on its own) 5 out of 5 times. The second test was our cowboy loads and it worked fine 10 out of 10 times. That is, two shells in it but firing the right barrel each time. So, it's sort of still broke but, on the other hand, it works for our purposes. My question: Is it still broke and it's just a matter of time until she gets bit by the dang thing in a match? Is there anything I can do to make it latch closed more tightly?
