While peep sights are probably the best answer, they are not allowed in any of the primitive shooting events I attend. It ended my competitive shooting about 10 years ago. Our primitive guns, with primitive peep sights, are not really competitive in the any iron sight catagory.
The pitty is that these sight rules were instituted years ago by people that were shooting origional guns, with their sucky sights, to keep new gun builders from outshooting them at matches. There is no historic basis for the discrimination between open and peep sights. It was a pol;itical move by the leaders of the NMLRA back in the early days of the organization.
Moving the rear sight foreward is not effective for whatever eye problem it is that plauges me.
I have found two things that work for me.
1. Widen the notch in the rear sight. It puts more light around the front sight and eliminats the "lost sight" syndrome I deal with. I still have to hunt for the front sight most of the time and then squint to line it up.
2. Use a shallow V rear sight with a large bright bead front. I am talking about 1/8" beads or bigger in bright brass or ivory. This has become standard for my hunting rigs.
Neither of these things really allows me to shoot the way I did before the eyes faded.
I use a scope on a magnetic base to work up loads, which is also frustrating. After using the scope to develop a fantastic load that centers POA with every shot, I remove the scope and find I can not keep the groups at half the size of the sighters.
I am finishing up a rifle that will have an open sight that works like a peep sight and conforms to the NMLRA rules. They state that the sight must be located at least 5" from the breech and if the rear sight forms a circle (Like a full buckhorn) the gap at the top of the horns must be a minimum of 1/4". This mandates that the peep circle be at least 1/2", but there are ghost ring sights with openings that large, so the experiment continues.
Getting old sucks! :cursing:
