peep sights improve vision based on the aperture effect . Look at an object then look at it through a peep. I got groups right at an inch with an M-14 and handloadsIn addition to Bell and Townsend, John Taylor also spoke highly of the peep sight. I used to have a bolt action with a Lyman 48 peep sight on it and could shoot 5 shot groups under an inch with it. It always seemed like magic to me the way they automatically work.
NECG front and rear (decent sized white bead, shallow V) is my preference as well (and yeah, my aged eyes are not as reliable with irons, either, but they nevertheless remain a strong preference).I am about to embark on another rifle build soon.. my intent is to use NECG front and rear sights (single leaf express.. I dont see a need for "long range" leafs on a .458 win mag.. and if I do need to take a shot at anything past 100 I will have a 1-4x optic on there as well)..
Honestly my eyes are getting a bit old for reliable use of irons.. I am much better with a red dot or a low power optic.. but, I also cant see building a big bore rifle that is intended for DG hunting only and not including a set of irons on it..
The same thing just the peep sight tends to be a smaller aperture more used in target shooting but you can get different size apertures that you screw in...if you take the aperture sight out then you have a larger hole which is easier to quickly picture up the target in a hunting /close quarter situation. That's what I did on my two 458 lotts....so a sort of ghost ring sight . ..but there are purpose made ghost ring sights madeSorry for reviving an old thread, what's the difference between a peep sight and a ghost ring??
