With interest I have followed this thread. I purchased these laser bore sights for 12ga off Amazon. The laser sights cam with batteries and a carrying case. They only sell them individually so naturally I had to get two.
All I have are American guns to test, no British. How to do this test so the results are the same with each different shotgun? With a sharpie marker I made arrows on the base and the arrows were at 12 o’clock. I used a shooting stick to hold the gun steady while my son marked the laser dots on the poster board.
I have a long hallway in my house. I can stand in my living room, and it is 25yards to the wall of my master bedroom. So I tested at 15yds and 25yds.
Here are the results.
