I have been shooting an A400 EXCELL for trap since late January, about 100 rounds weekly (or more some weeks) with no problems until Saturday when I had a double fire with one trigger pull. Research on lines suggests this has been previously reported, variously attributed by some to light hold, and to bounce off due to the "Kick-Off" recoil reduction stock. I wonder if anyone here has had that experience or can suggest a cause.
