I had a NECG on my 450/400 and switched to a Skinner. With my loads (400 gr. @ 2120 fps) I got 1 1/2" low @ 100 yds, raised the sight 1/2 turn (the minimum amount) and the group was 4 1/2" high with the NECG sight. Switched to the Skinner and it was about the same distance (6") with half a turn. However, the Skinner lets you see a whole lot more because it doesn't have the "ears" that the NECG has. I did then go to a shorter (by 0.033") front sight that I had to purchase through Brownell's and I am exactly at point of aim at 100 yds. now. Either sight makes, in my opinion, the No. 1 much nicer to carry than with a scope and, I think, the lines are preserved. Both being aperture sights, the target acquisition is very fast. Good luck with whichever you decide. Terry
