I know what you mean about the spot looking so small on these targets. The red center of those targets I use is 3". At 100 yards the lyman post ball completely covers the spot. All I do is try to center the post in the target at that distance. It seems to work. I am going to go to a little smaller post from a Lee Shavers insert card and see how that works on a black background with red circle. I do know one thing, there is no way I could shoot this good with standard iron sights, the peep helps a ton. I think if the barrel on this rifle was 28" instead of 24" it would help a little more. Matter of fact, I've thought about picking up a trade rifle barrel and dropping it in this stock just for that reason. Get that sight out farther where I can focus better, I can't see to read without glasses anymore but for distance I'm good.

Any way, I'm finding that all the experimenting is half the fun.
