1873 springfield trapdoor factory carbine rear sight

If I need to, I can raise the rear sight and set the crossbar on the curved ramp for longer ranges, or Lots to places to shoot out to 100 yards or so, but longer ranges not so much around here. Still can fit the bayonet on it over the 'extended' front blade if I want to, so I'm happy with it. Nice at about 100 yards with the sight all the way down (using the sighting groove in the base). Reinstalled the sight blade and worked it just a leeetle bit with a file on the top, and now it shoots real Then hammered the thing out flat so that the new 'top' on the original sight blade was the same width as the rest of it. I poked out the pin holding the front sight blade and laid a silver solder bead on the top of it, True to originals, it shot way high at closer ranges than about 300 yards, with 400 grain lead I shoot an old original 1873 Trapdoor rifle. My sight blade is pinned in and I'm going to fabricate one to use at shorter ranges. Yep, I have a late model cadet trapdoor that shoots high as they all do at shorter ranges. (Be sure to keep the original front sight so you can replace it if you ever want to sell the rifle.) Keep in mind that if you sight in at 100 yds, you will be hitting significantly lower out at, say, 300 yds. The alternative is to replace the front sight (most of them are pinned in the sight base), with a higher front sight blade.

targets one above the other, and aiming at the bottom of the lower target, should get you 'on the paper'. As Smokin D recommends, placing two 8' dia. military rifles and carbines were 'combat sighted' at 352 yds (+ or - I don't have my references out, but that's close), depending on the loading (70 gr for the rifle cartridge, 55 gr. bullet, even if you load with the heavier slug, the rifle will shoot 18-24' high at 100 yds! The reason is that virtually all U.S. Presuming you are shooting an origianl Trapdoor Springfield, although you are shooting a bullet that is lighter than the original 405 gr.
