hello, got a lyman peep sight setting on a mossberg 44 (b). need to know what size aperture is best to use for general target shooting? mostly i guess around 50 yards and do i need to change for different distances? also, any differences for hunting as opposed to targets. thanks for any help.

  Different size apertures are needed for different light conditions. The lower the light the larger the aperture needed. (aperture meaning the hole in the disc). Generally, for hunting you will need a larger aperture. I deer hunt with a .30-'06 with a Lyman 48 rear sight. I screw out the disc and aim through the threaded hole. That is plenty accurate for deer hunting. For small game it might not work. Go and shoot some while aiming through the threaded hole only. You will be surprised how accurately you can shoot. That is assuming you can hold steady and don't jerk the trigger.
  
  Added: The variable that necessitates different size apertures is the light condition only. It doesn't have to do with distance to the target.

  Herschel got the bigger part of the picture, however, the shooters eye distance from the sight and the clarity of his vision will also determine the most desirable aperture diameter. There is one made that has a provision for altering the hole size over a wide range..Merritt as I recall.

  Edit: Looking through an aperture at an object has a similar effect as does looking thru a lens, it tends to focus the object. On a camera, the aperture opening is refered to in F-stop values. The smaller the opening, the less light but also the greater the depth of field (better in-focus range from near to far).
  
  On a sight, one wants the front sight in focus as well as the target. If properly spaced from the eye, it will be natural for your eye to center your viewed objects within the aperture. As target shooting tends to be at set distances, the need will differ from a hunter's need for a wider range of distance. Also, not all of us geezer's eyes are all the same, so choices vary from person to person as widely as do choices of caliber.
  
  Two ways to go about trying & finding what works best for you,
  
  1) buy the smallest aperture & with a set of number drills, gradually increase the center hole till it works well for you.
  
  2) buy an adjustable aperture & when you find the best setting for your needs, measure & build or buy a solid aperture for everyday use.

  In a nutshell, for the most repeatable sight pictue you should use the smallest aperture possible based upon the amount of ambient light and eye relief required.
  
  This refers to target shooting only. Field use on possibly moving targets is a different story.

  Merrit Optical is the place to go...their adjustable aperture works with most threaded peep sights. I believe that Dixie sells the adjustable aperture made by Merrit as well.

  That's a great website - added to my favorites, no more looking around Midway or Brownells for plastic apertures for me anymore! Thanks

  the smaller the aperture, the more accuraCY. THE LARGER, THE FASTER TO SIGHT. (fat fingers hit caps lock) hunting accuracy is adequate with 1/8 hole.
