sight adjustment from indoor to outdoor

so i'm about to embark on my first actual competition on 2 september (yikes!), but i've been practicing indoors and my first shoot is outdoors! is there a good general rule for adjusting sights from 50' to 25 and 50 yards? if it is relevant, i'll be shooting a 1959 vintage high standard space gun with the 8" barrel.

You didn't say if you were using irons or a dot.
If a dot, come up 3-4 for 50 and see what happens.

If Irons, the light may have a much more significant effect on your windage adjustment but depends on the range and time etc.

When you get your zero's make sure and keep sight setting for each range/distance/ammmo so you have something to go back to when you return.

d'oh! sorry, yeah, i'm shooting irons. thanks for the info, though. it would have never occurred to me that shooting outside would affect the windage adjustment. how much change should i see in elevation?

I would start the same 2-3 clicks or so up and see where that puts you.
Then, the old saying 'lights up sights up'
If it gets brighter, the black 'appears' bigger and a 6 o'clock hold will drop a bit lower. More true with rifle due to the distances.

Sun on your right puts a shadow on the left side of the front sight causing you to shoot a bit right so give some left windage. Reverse for sun on the left.

More, make a mark on your sights you can define as 0 and as you get the exact settings for the range note your new position.

It's different for everybody. I know folks the don't change anything from 25 to 50 and those that change 4 clicks. Also, depends on if you load for the distances. 22 I shoot the same ammo, .45 I shoot different loads at the two distances.

thanks for the info!

so that's 2-3 clicks from 50 feet to 50 yards, right? my .45 is at the smith currently, so i'll only be shooting the .22 portion of the match, so i don't have to worry about changing loads or anything.

i will let everybody know how it goes! of course, i don't have classification yet, so i'll be shooting in the masters' group. at least i know i won't have to worry about bringing home any trophies
