Your thoughts, considerations and experiences on aperture and post sizes, I recently discovered the phenomenon of "spider-webbing" on too small of an aperture, so you can go too small... On front post size... I currently have a standard (or "original") A-2 post 70 thousandths of an inch. Shooting 100 yard reduction targets, bulls eye is just about the size of the top of the post holding 6 O'clock, getting smaller as we progress to slow prone. I noticed that shooting my '03 A3the very thin blade sight was not too bad and the sight picture looked more like a lolly-pop. I believe I will settle on the .46 hooded rear aperture, but would input on experiences and science of front post size. Thank You.

I have a R.R.Arms Nat. Match Ar15 w/hooded aperture on an A4 handle, and NM front Sight.
It's just right for me w/60yr old eyes. I've only shot it at CMP Talladega under the covered shooting positions, but really like the set up.

Pottimus – If you are shooting with a six o-clock hold, most people would use a .050 front sight. It should show up as the same width as the bull. The .072 is what I use, but I shoot center mass. For us old guys that use a center mass hold the wide post will overhang on each side on the bull so we can keep out shots centered. A NM front post will help a lot as well. They are tapered front to back so all you see through the sights is the front face of the sights. With a standard post sunlight will shine on the side of the post and can move you around on target. Sight black helps quit a bit as well.
As for the rear sight. I like the smallest aperture that stays light. I keep a .036 and a .046 in my bag. I keep a .040 on my gun. Around here, the .040 is generally fine. There is one range I use the small one at. That range is basically a sand pit. Its like shooting on the sun its so bright. The large aperture is basically for shooting in the rain. Most of the time the .040 is fine and gives me the best sight definition. If you go big, aperture wise, your scores will suffer. You didn't say what size gave you spiderwebs or the lighting conditions on that day you saw them. If it was a bright day, yes you will want to go bigger. If it was a day that was darker than average, you may want to hold off.
At any rate, welcome to the High Road and welcome to High Power.

The RRA Hooded.30 was the one that was bad, light conditions are normally bad at our range anyway, but last match was worse fog ever. So I guess I won't give up on it yet. I have got in a .46 (too late for the match) and I might as well get a .40. I have tried center Bull but went back to 6o'clock for years at others coaching, I was not told of the use of a wider post to achieve consistent sight picture, rechecking front post it looks more like .62 no taper, for me there appears to be no extra post protruding beyond the bull until the prone positions. The wisdom and experience you have shared are welcomed and appreciated. I believe i may try a smaller post and the next bigger. The trigger time won't hurt.

match sights
I am a little bit unsure about whether you as discussing sights for HP Service Rifle matches.....that was what I thought when I read the first post.
My initial thought, though, was that info was needed about sights for HP "match rifle" competitions. In that type of high power match shooting, often both the front and rear are apertures.

Gotta find what works best for you...most of the time I shoot an .038 rear and .062 front post (NM taper). At times (heavy overcast/rain) I switch to an .042 rear.
