There was no explanation for why the site was down on its front page and and it appears that it has not been updated for some time. I don't know what the deal is other than its a great site for doing some quick reference for those milsurp rifles you may come across. I was finally able to look up the 1903 Springfield I have and look what I found concerning that pesky ladder sight: (Cut and paste from surplusrifles.com, all credit to the writer there for the info contained)
I found the rifle's rear sight was fairly complex and I could not figure out which notch or aperture to use. So I set off to do some research and this is what I found.
|To use the rear sight's adjustable notches or apertures the sight leaf is lifted as shown in figure 3.|
|To adjust windage (left or right) turn the windage knob (as shown in figure 4). Each graduation marking equals 4 minute of angle at 100 yards.|
|I believe that the 1903 has one of
the most accommodating rear sights found on any early 20th century
Imagine a sight being produced for a rifle with no less than
5 sight notches and apertures (3 adjustable and 2 set for specific
To adjust for elevation loosen the elevation knob on the right and then slide the aperture up or down (as shown in figure 5).
Figure 5 shows a type 4 sight leaf with graduations from 100 to 2825 yards. The 1903 had seven different leaf types (ranging in max graduated distance from 2000 to 2825). The leaf's left side scale ranges from 200 to 2820 while the right side scale ranges from 100 to 2825.
|Figure 6 shows the 1903 battle sight picture that is set at 400, 530, or 547 yards (depending on sight type and cartridge used). The battle sight was used for the following: A soldier using the battle sight could hit a man between 100 and 400, 530, or 547 yards (depending on sight type and cartridge used).|
Wow, that is just the info I needed for that rifle!! A maximum range of 2,850 yards! Who could see that far? Not many people, it was actually more likely intended to be used to volley fire great distances at advancing cavalry or other such troop formations to create a beaten zone of fire for the enemy to advance through.
