The 470 and 9.3x74R barrels have the same serial number as the receiver. So these were a set made by the factory in Germany. I have the test targets, as they were included in the box. The 7x65R barrels carry a different serial # manufactured a couple of years earlier. I never fired it, as soon as I got it I brought it in for the stock work.

As soon as I get it back, I was promised before Christmas
and get a chance to shoot them I'll report back.

As far as the shotgun barrels go, I'll probably add them as soon as my wife gets over the shock of the cost of the gun
