This 725 is only 6 months old. About two months ago the bottom barrel started not firing but only when the top goes off first when using loads less then 1 1/8. This video shows 7/8 loads. When firing straight ahead or upwards the trigger hangs for the second shot almost every time. But when pointing downwards it doesn't catch and fires fine. When using 1 1/8 loads it must jar something enough that it isn't catching on anything YET. Receiver has been apart and cleaned many times. Not sure where to look next or what to ask of a gunsmith. Ideas?
