All this talk about sights being offset from the barrel has little to do with it. Even if the bullet traveled parallel to the line of sight it would only be approx. 1 in off. I don't think a gun of this type or even a cartridge firing double rifle could fire a group of less than 8 to 10 ins.at 400 yds. with express sights let alone with clamp on sights that would change with recoil. I must admit it is puzzling. Does this rifle have rifling or is it a smooth bore. I would think you would have a hard time hitting pig at 400 yds. let alone any further. I hope some one figures it out.
