Seeking information on the correct manner to engage an existing ladder sight on a Winchester Model 1894 rifle; i.e., do you first remove/loosen the tension screw holding the ladder sight in place, slide the ladder sight forward and lift up? 

Seems obvious however, do not want to compromise the sight itself or the tension screw.

Also, assume the numerical graduations on the ladder sight itself do not equate in any manner to corresponding and correct yardages?

Thank-you.

They is no screw you have to loosen to raise or slide the elevator. The ladder should snap upright and stay by the spring action of the lower leaf against the barrel and the elevation slide is held by friction.

Bob, thank-you. Will try that. Any ideas regarding the numerical elevation scale on the ladder sight and corresponding distance accuracy?

I don't do a lot of shooting and never tried to figure out the sight elevation marks but they were put on them for a reason and I would assume if you used the original loads there is a correlation.

If they corresponded to specific ranges, wouldn't there have to be different ladders for each cartridge?  That seems rather improbable.

Folks,

  I believe the difference in trajectory for the differing calibers in the black powder era was not that great, plus the front sight could be the element used to tweak the rifle for the particular caliber.  I believe, though have not confirmed it by shooting original ammunition of course, that the yardage marks were close to what was needed for the caliber/cartridges in use at the time.  The little I have done with the .45-75 with mild loads shows the ladder sight and its yardage marks to be close to being correct out to 200 yards anyway.

You have to shoot your gun a lot and figure out what mark means what.

Exactly what users of Lyman tang sights were expected to do--the markings on the staff had no "meanings" with respect to range.  You fired at some range of your own choosing, moved it up one index mark, then fired again to find out how much higher the group had moved on the target, & so on.

That's actually how the 82A ladder on early 52s worked, & it's reasonably accurate.  However, it was calibrated for one bullet wt at a standardized velocity. Shoot lighter or faster bullets, & its accuracy breaks down.

Thanks to all for your varied and educational input. What I assumed to have been a simple answer turned out to be more involved, insightful and thought provoking. Would expect nothing less from all the SMEs on this forum!
