1) Make sure that the front ring is in perfect focus. The sighting radius is approx. 1 mtr and your optometrist should check this for you. For older shooters that need a lens or shooting glasses this may mean that the reading and distance vision are somewhat blurred but the 1.0 mtr focus is crystal clear.
2) The rear peep should be roughly 1.0 to 1.1 mm. Too big and your group will open up, too small and the sighting picture will be too dull. Once set I can't recall ever changing this no matter what the sighting conditions.
3) An eagle eye is almost essential these days. When they became legal I used a 0.3 for a while and then went to 0.5. I never went back. There are some negatives like greyer, slightly blurred aiming mark and any rifle shake is magnified. However the upside is that you have a bigger blot to aim at. Another plus is that it helps to see the target numbers at long range.
4) Ring sizes should be big enough to allow you to accurately centre the aiming mark even if it does look a bit grey and blurred. You need plenty of white around the aiming mark. Too small a ring might look good but generally it just doesn't work.
5) Filters can improve the picture. With bright light (sun) on the target a light brown filter works well. In dull light a yellow can improve the contrast between black and white.
6) The sighting process is to focus on a crystal clear foresight ring with a perhaps greyed and blurred aiming mark in the middle. All other things being correct, as long as your sight picture is consistent from shot to shot you will be amazed at the tight groups you can shoot.
This advice is absolutely correct & agrees 100% with my findings over 40 years of T/R shooting. Most newer shooters use rings that are too small, these will often work O.K. in perfect conditions, but most definitely not in the long haul, if in doubt, go bigger.
