How much adjustment will get me in the ballpark to bring the round up 12” @ 50yds?

3.7 degrees
If you want an answer in inches one would have to know how far apart are the front and rear sight.

That's a lot. You may have to go all the way up on the rear sight bridge. If that's not enough you may need a shorter front sight.

I’ll start there, there’s quite a bit of adjustment so hopefully it’ll be enough. Aiming at the kill zone and missing completely. Had to go to the top of the shoulder to get in the zone.

what is the gun

sight radius is needed to calculate

taller front sight would make it better unless your rear is all the way up

most rear sights need to be almost all the way down on factory guns with normal ammo for that gun.

Don't you mean a shorter front sight Pete? He's already shooting low.

This is a website that uses the geometric sight correction formula. Plug in the numbers and get your answer.

yeah i read that tooo fast , I saw top of shoulder

what is the sight made out of he may just need a file
many muzzle loaders with bras front sight blades come excessively high (shooting a foot low at 25 yards) and a fine file is the tool to adjust them down

My flintlock was like that. I replaced the front site with a shorter one. Just needed to know the size of the dovetail and sight height of course.

If your gun is shooting low, drop the rear sight down a little. Then continue to test and adjust as you see fit. A good rule to follow with iron sights is, follow the bullet. Which means if you’re shooting high, raise the rear sight or if you shooting low drop the rear sight.

That is incorrect, you have it backwards. Always move the rear sight in the direction you want the point of impact to go: raise the rear sight to raise the point of impact and lower the rear sight to lower the point of impact.

One of you must be an ammo salesman. lol

Well it ain't me, I steered you straight Hobbie.

lol

I hate when a good rule goes bad lol

Sometimes good rules just ain’t what they seem.

do you know the right hand rule for scopes

If you want to go up with the shot place your thumb on your right hand up , your fingers now tell you which direction to turn , ditto on down , and need to go left , thumb points left and fingers tell you direction to turn dial

it works till you find a backwards scope , but it works on most scopes sold in the US

you military Irons are left hand point the thumb the direction you want to go , you find exceptions to that rule a little faster than scopes.

Sorry! That is what I learned and for some reason it worked for my .22.

Obviously Lugnut knows a lot more about it than I do, so don’t pay any attention to me!

I just reread our posts. They both say the same thing but with different wording. Check it out and let me know if I’m wrong.

We are not saying the same thing.

You are saying raise the rear sight if you're shooting high and lower the rear sight if you're shooting low. That is incorrect and opposite of what I'm saying.

Here is the rule (the real one): Move the rear sight in the same direction that you want the point of impact to move.

If you want to raise the point of impact, raise the rear sight. If you want to lower the point of impact, lower the rear sight.

On rear sights that have windage adjustments the same rule applies: Move the rear sight the same direction you want the point of impact to move.

If you want to move the point of impact to the right, move the rear sight to the right. If you want the point of impact to move to the left, move the rear sight to the left.

What you are saying is actually correct for FRONT sights, not rear sights.

All adjustments to front sights, both windage and elevation, will move the point of impact in the opposite direction of the sight adjustment.

I was trying to save a bunch of thinking by asking but y’all figured out a way to make me do it anyway. lol

What does a picture of a constellation have to do with adjusting iron sights?

here is my crude drawing to make this make sense to people

your line of sight is a laser strait line
the gun needs to be angled slightly to get the bullet up through your line of sight and then back down
that is near zero and far zero
with a 22lr and a 1 1/2 inch height over bore zero at 25 yards , a little high but less than a squirrels head high in between and back to about zero about 50 yards

the rear sight if adjustable is a protractor setting the angle of the rifle in relationship to your line of sight. raising the rear sight angles the gun mor muzzle up , in reference to the line of sight.
military ladder sights are an excellent example of this you can see the graduations and you can see they get farther apart for 300, 400, 500 ect

you can adjust rear or front sight on some guns and only one or the other on some guns
what you are looking at is if I lower the front sight I actually change the angle of the gun higher
if I raise the front sight I change the angle of the gun lower

LOL

Y'all could write a dissertation on how to change a light bulb......

This. It ain’t rocket science.

but first I would need to know what base type , use , voltage , current , heat ratings and some other stuff.

the assumption that all light bulbs are 120vac Edison base makes it sound simple but assumptions are no good , the rule is broken as often as it is kept.

The knowledge, the lack of knowledge and the want-a-be's on this thread is quite amazing and amusing. lol Carry on.

Ok. I get it now. It’s the front sight that should follow the bullet while the rear sight moves in the opposite direction of where the bullet is hitting. Sorry again!

Like me!

Lol

No. You move the rear sight in the same direction you want the bullet to go. Move the front sight in the opposite direction.

Not the ideal situation, freestanding @ 50yds but this is how it went down.

1. Aim was top of the red dot. (Was just hoping to get it on the tin)
2, 3,& 4, were red dot aim after 6 clicks up on rear sight, 3 clicks right.
5. 3 clicks down.
6. 2 clicks left
7. 1 click right, 2 clicks up.

Get the bench out Friday and do it again

You really should get on a bench and shoot three-round groups to sight-in. That will give you a much better idea of where it is shooting. It will also tell you if your .22 likes that particular ammo. If it does (nice tight groups), get it shooting where you want and stick with that ammo.

Yeah, I should but didn’t have that kind of time available this afternoon.

what red dot is it ?

IMC Inches Minutes clicks

turn the dot intensity down as light as you can see it still this makes for a finer dot

at 25 yards ever 1/4 inch is a minute at 50 yards 1/2 inch is a minute

most red dots are 1minute clicks a few are half minute clicks

shoot a good group of 3 measure from POA point of aim to POI Point of impact

a little figuring and your next group can generally be at POA=POI

Do you actually read or just skim over?

ahh the red dot not the red dot

when your talking irons then say red dot and clicks , aw never mind I am going back for another beer and will just give up on reading tonight

lol….

New problem.

I need my bifocals to see the sights and the other part of the lens to see the target. Too much head movement, gonna have to send it back. I knew I should have just bought another guitar.

Iron sites are not for those with old eyes.

Can you put a peep site rear on it?
Would help immensely with the vision issue...or a small holo type sight...

what gun is it peeps make it a lot better because the front sight is far enough away that it is in long distance vision

Has a peep sight on it, big hole or little hole, it doesn’t matter. Shot 9 rounds of 3 groups each (27 shots). Only managed once to get all 3 in the circle. Shooting from the bench with sand bags.

You have a bigger problem then just the rear sight, lol...try different ammo?

I can’t see. The more I shot the worse it got. lol

Speaking of ammo, should enacted shells be ending up in close proximity of each other?

from a semi auto , if your stationary shooting at the same target the ejected rounds should land in an area about the size of a hula hoop they may bounce

when we test ammo , a good load will often make a pile that you could cover with a 5 gallon pail for 10 rounds.

the last round often ejects a little different because the way the next round isn't pushing up on it

wild ejection pattern can be signs of ammo with a large deviation

it might be time for an optic

another thing you can try is a diopter
https://bulletin.accurateshooter.com/2012/07/diopter-devices-aid-old-eyes/

a friend who shot service rifle irons had one and claimed it made a big difference.

another friend's advice to pistol shooting with irons was figure out how long it is from eye to front sight, go get a pair of readers that let you see clearly at that distance , now you have a crisp front sight on a blurry target , just go for the middle of the blurry bullseye with your crisp sight

both of them were in their 50s at the time trying to figure out how to keep doing what they had enjoyed

my eyes haven't gotten there just yet
I also wear glasses and tell the eye doctor what I am looking for in shooting glasses. he made a few tweaks after I explained so far working good as long as I have the glasses on.

That’s a flag then. Parked the truck right next to the bench and most of them ended up in the bed but some went over it and 2-3 bounced off the side never made it in.



That looks ridiculous lol, but I’m gonna have to try it.

Thank you all for your time and patience.

308?
what ammo?

What you are trying to achieve is not possible even with fully functional 20-20 vision.
For accurate shooting, focus needs to be on the front site. It needs to be a sharp image. Once you have that, the target will always be fuzzy. Your job is to simply place the top of the front site post in the middle of the blurry target.
If you do that, and your rifle is capable of accuracy, your groups will tighten up.
