I put a Williams peep sight on my rifle and went out to the range to test fire today. Windage was great, but, it shot about 16" high, of course, I forgot to take a screwdriver to adjust. On the way home I was trying to remember if you need to lower the rear sight to lower the point of impact or raise it? I am thinking it need to go up at the rear to lower the poi. If it needs to go up, I am good to go if not I need to look at a new front post, in which case, do I need a taller front post to lower the poi or file down the insert to lower it?

Lower....I think.... I usually sketch it out when I can't remember...it helps.

rear sight is your friend, to lower the point of impact, lower the rear.
Peep sights usually end up requiring a taller(to lower the poi) front sight.

I have a Lyman target front sight so I need to make a new insert or buy a taller one it seems. Maybe I should stick to a scope.

Always move the rear sight in the direction you want the bullet to go.

Trying to do trig, if the target is at 100yrds, and the distance between sights is 22", then the front sight needs to be 1.15" taller

That can't be right? can it?

That can't be right? can it?Mmm 0.100"-ish?
15" over 300 feet= xx over 2 feet
300/2=150
15"/150=0.1"
I think. I can't really brain today.

And yes, move the rear sight the same direction you want the bullet to go.
Make sure to loosen the clamping screws before trying to adjust, too :red:
Still feel silly about that one.

Well duh yea, for some reason I thought I did it in feet(aka brain fart) and times the 0.1 by 12 to get 1.15
So I did get 0.1 too, and then I proceeded to ruin the correct answer.

I like your math, because I found an insert for the front sight that is 1/10" inch higher. Given I have no downward adjustment on the rear and the good folks at Brownells told me this combo works, the 1/10" higher front insert maybe the ticket.

Found a set of weaver bases and put them in the range bag with some tools. My buddy is going to let me try his scope and rings. I installed the higher front sight insert and I will let you know how things go after the next range day.

Thank you folks, it all makes sense when I am given the answers.

16/3600 = x/24"
16x24/3600 = x
=0.1

that's more simple than my way

At 3600"(100yrds) the sight is off 16", which for an angle is 0.25degrees.
Taking the degrees, we change the horizontal to the sight distance, 24" and Tan angle = O(sight height)/A(sight distance)
So Tan 0.25 x 24" = 0.1

I am many things.
A bit simple is right near the top ;)

Curly! What's the rifle anyways?

Can I sneak a question in here about rear sight elevators? My new-to-me Marlin 94 in 44mag. loses its elevator piece when fired. Luckily I was firing it at the range so it was an easy find.
Second time it fell out it went into my front pocket. It's at it's lowest setting so it doesn't have much tension on it. Any easy fix for this problem, thank-you.

Might not be the correct way, but I'd remove the rear sight and if possible bend it so that when it's put back in it'll have more downward tension.

The rifle is a Parker Hale Safari that I am thinking of selling. I wanted to sell it with good irons, but, the originals are AWOL. I had the Lyman and when I called Brownells they said the Williams WRGS would work with the Lyman on this rifle. I thought someone would buy a light weight 30-06 with good irons for a walking rifle. Well I got the light weight rifle and boy is it a natural combination on the rifle, now I just need to make it work. I have been told the Williams can be made thinner if the taller insert doesn't work or I can buy another taller version of the Lyman(of course Brownells is only to happy to toss one in the post). Frankly, if the taller insert is not good enough, I'll put the weaver bases on to use up the few rounds of 30-06 I have and sell it a little cheaper making sure the buyer is aware of the issue.

That's how I'd do it.

Thanks blacksmithden and lone-wolf, I'll give it a try.

Ok, so off to the range with the new 1/10" higher post and she is only 4" high at 100 yards. Still a bit high, but, you could hunt with it and would be pretty close to zero at 250. Thanks guys, still a bit high, but, I'll let the next owner do the fine tuning.

Got the rear sight off and the leaf bent down, now the sight fits too loosely on the dovetail. Any suggestions to get it to fit tight? Thanks. Sorry for stealing this thread again.

If the dovetail slides out, flip it over and give it a couple of dimples with a centrepunch.
This will create a little lip on the 'crater' and will tighten up the space.
