Went back to the range today with the gunsmith who is also does Heym Warranty Work. We loaded the .470NE (1 loaded, 1 blank) and YES both barrel did shoot when using the front trigger first. If using the rear, only 1 barrel shoots. So he is going to look at it and see what he can do. He is VERY good at his work and has worked on many nice and complicated guns.

As for hitting the target, the Heym .470NE is shooting slightly to the right about 1.5" but it is centered. Once we get the gun back (Gunsmith took it) we will test it out again and see how it does. We are also having the gunsmith install the claw mounts with a Swarovski Scope.

Thank you everyone for their help! I'll keep you all updated when my Dad gets his gun back.
