I can't speak for MojoHand (and really don't want to steal his thread), but I went to the range the other day and zeroed mine at 100 yards just using a standard paper plate on a black background. The plate showed up just well enough around the front bead to make it pretty easy to get right on. 3 shots went into 0.61" using a 400 grain bullet that chrono'ed at 2124 fps. I should also mention to actually get it right on at 100 I had to put in a NECG front bead on that was 0.03" shorter than the original sight. The Skinner minimum change at 100 yds (1/2 turn of the aperture) was just about 6" with my load. With the stock front sight impact was 4 1/2" too high or 1 1/2" too low if I turned the sight down, therefore the change with the front brought it right in. And, all this shooting was from a bench. I shot with the standard aperture that was sent with the sight. However, I plan to take it to Alaska next week and I'll hunt with the aperture removed.
I initially tried a NECG rear sight that went onto the rear scope groove, but didn't care for the "wings" on that sight blocking some of my overall image. With that being said, if you plan on taking a scope thinking you might want to use it, the fact that the NECG rear sight would just unscrew and you could screw on your scope, I think, makes it a better option because the Skinner requires you to screw it in thru the sight rib and you have to exchange the slotted screws for the Skinner back to the original hex screws. Hope this helps. Terry
