On the Boss O/U the top barrel always fires first. It would dent the primer and even eject the shell. It would not always happen. What is the cure? Mike Proctor

Consider the angles involved in the OU lockwork pushing that pin at a sharp angle. A small pin adjustment can make a big difference if switching ammo batches/brands doesn’t fix things. Owen

I agree with you on the angles of the Boss OU firing pins. They don't agree with a lot of modern ammo. The ignition issue is a common problem. Same with extraction, especially on vintage guns.
