93:

Your original post involved extending the range of usefulness of your Merkel beyond 50 meters, i.e. beyond what the fuzzy sights allowed. That is also what caused me to search for a sighting option for my rifles. Anything worked OK at 30 or 40 yards, but on targets the size of a whitetail deer {or some of your game there I suspect} at over 50m, there must be an increased amount of precision.

For some samples of groups shot with my prefered sights, here are two 5 shot groups fired with a Husqvarna M648 8x57 while zeroing it. Both were fired at 100 meters from sitting on the ground, elbows rested on knees.

You can see the sights on this rifle in the picture posted earlier. It is the rifle on the left. Sights are a thickish blade front, notch rear. The rear notch is wide enough that lots of light is visible on either side of the front sight blade.

When there is a fine aiming mark as exists in the "Facing Deer" target, very fine groups can be made. But deer do not typically possess a very fine aiming mark as you know, so most of my shooting is done on targets not possessing such, as is found on the larger target which is the Norwegian reindeer target {annual hunting test target}. Rotating the target somewhat sideways will also help you test sights, as will shooting in bad light.

These targets give an idea of the results I get with the sights I prefer. The blade front can be painted any color you like. In the field I use black or I white out the front blade if lighting is very dim. These sights are very easy to pick up against a variety of backgrounds, and the flat top of both front and rear provides a sharp and repeatable aiming point. Speed in acquisition comes from making sure there is light showing on either side of the front sight. Too narrow a rear will provide an acceptable sight for the range, but a poor sight in the field.

The sights you show on your Merkel might be close to what I would like except I'd throw away that front sight and mate the rear with a thick front blade, though one that is narrow enough to allow lots of light on either side. It is hard to tell if that is possible from the picture. I would also blacken the dots as I do not like white dots in general, though for very coarse work I have used tritium "night sight" inserts on several of my pistols with ok results.
