This happened yesterday while sighting in a 34 and 19. I was sighting a red dot on the 34 and had my elbows supported on a shelf at a range. My "suspicion" is that I must not have had as firm a grip as I usually do in normal shooting and the LAX loads are rather weak. I also had one failure to ignite the primer-dented but not fired. It fired the second time i tried that round. Next time at the range i will be sure my grip is firm. Does my suspicion sound like the likely cause of the trigger not resetting-once with each gun? Any experience with the LAX ammo?
