My rifles do have the Lyman 57 SML sights. A lot of guys think they don't have time to change sights. In that case if you know you will be shooting 100 yards or less set the sight at 100 yards. In the case of my 409 gr bullet. The highest the bullet will be above the line of sight with a 100 yard set on the sight would be 1.80" at 50 yards. At 125 yards it will be 3" low. If a guy just puts it on 100 and shoots for dead center your good to go on those, got to do it now shots.

Personally I have found that when I spot and stalk I have PLENTY of time to use my range finder get the range set the sight and take the shot. In the case of my antelope I shot I had the yardage set to the water hole and when he walked up I had the sight already set at 89 yards or close to it, and I just shot him.
The nice thing about the Lyman peep is it's versatility. You can use it as a fixed sight or a instantly adjustable vernier tang sight capable of long range shooting.

I don't normally take long shots either. But on one hunting trip a friend of mine wounded a buck. We both had tags so it was legal for both of us to shoot at this buck. My friend shot it and wounded it. The buck took off and we followed it up. I took a shot at 175 yards and hit him solid but it was still on his feet. My friend shot and the buck moved off un-hit by my friends low shot. I was reloaded and hit the buck again at 185 yards. The buck went down and stayed that way.
Had I not been able to set the sight for that yardage I would have probably missed like my friend did. But since I was able to to set the sight for that yardage the buck was not lost.

I don't think that the Lyman sight is the perfect sight for everyone. I do think that for my style of spot and stalk hunting they are the perfect sight for me. Case in point. In this picture I wasn't aiming at the milk jug, I was aiming at the label, the shot was 150 yards. Ron
