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.
