Sight adjustment on Marlin 336?

Which direction do you Slide on iron sites when the rifle shoots high? One more than 336 shoot high and I was moving the rear sight higher. Should I have lowered the rear sight instead? I went through two boxes of ammo today and never could really get the 336 dialed in. By the way, the rifle was made in 1976 so it's not a "Remlin".
 
Yes, next time out, you'll want to move the sight down. I try to remember it this ways: Move the rear sight in the direction you WANT the bullet to go.
 
Exactly what 10-96 said.

The rear goes in the direction you want it to go and in the case of sights that can also move up front you move them toward where the bullet impacts the target.
 
Elevation

Higher front sight, lower bullet impact
Lower back sight, higher bullet impact
Take a moment and think, higher front makes you depress muzzle to get sight
picture. Lowering rear makes you elevate muzzle.
It's simple when you think about it.
 
Higher front sight, lower bullet impact
Yes.

Lower back sight, higher bullet impact
No. As others have said, the point of impact moves opposite to the direction you move the front sight, and in the same direction that you move the rear sight.

Take a moment and think, higher front makes you depress muzzle to get sight picture. Lowering rear makes you elevate muzzle.
Again, yes and no, respectively. It's simpler to envision raising the rear sight a lot - as in a few inches, which of course isn't really possible - which makes it easy to think about what you need to do with the muzzle to get the front sight lined up again, i.e., raise it a lot, which will raise the point of impact.
 
For something so simple, it is easy to get confused when all you have is words. So get a prop. Pen, pencil, stick, ruler, anything longer than it is wide will do, even a .30-30 shell.

Point it at something. Hold it in the middle. Where you are holding it is your FRONT SIGHT (and we aren't moving it)
the end away from you is the bullet impact, the end toward you is the REAR SIGHT.

NOW, which way do you move the rear sight to get the bullet impact to go where you want it?

If the gun is shooting high, you want the bullet to come down, so push the "bullet" end of the pen down, where does the other end go? UP!

Hope this helps.
 
great advice!!

Thanks for all the helpful advice. I which I had made this inquiry before "wasting" a couple of boxes of shells. Live and learn; and ask questions before a task--I should have known this by now.
 
Here's a link to the CMP article on rifle sight adjustment:

http://thecmp.org/wp-content/uploads/Gary_OTMFall2011.pdf

The important part is the second paragraph of the second page "Sight Adjustment Principle" where the author makes it clear that the point of impact moves in the same direction(s) as the rear sight is moved. As I read 44 AMP's example, it seems to say the opposite, but that's just simply wrong, so I have to assume that I'm not understanding the example correctly.

DRM 50,
Look at your post above. I think you lower the back sight to shoot lower and arise it to shoot higher. Right?
 
It is a matter of relativity, meaning, the description of "which way the bullet moves" is relative to your point of view. And, of course, this sounds confusing...

Your line of sight is just that, a line. Back sight, front sight, target.

Case in point, rifle is shooting high, meaning bullets are hitting ABOVE the point of AIM. The line of sight goes to the point of AIM. The object is to move the line of sight, so it ends at the point of IMPACT, making the POA and POI the same.

TO do this, you need to raise the POA up to meet the POI. Since it is a line, to raise one end, you lower the other (rear sight goes down).

BUT, when you do this, what it looks like on the target is that the bullet impact seems to move DOWN to the point of aim. In reality the bullet still hits in the same spot.

The people saying move sight opposite are looking at how you move the line of sight, the people saying move the same direction are looking at how the bullet appears to move on the target.

Both are actually correct, but only if you realize their frame of reference.

If its not as clear as mud, now, I can elaborate...:rolleyes::D
 
I'll say it again: ;)

- Move Front sight to where the bullet WENT.
- Move Rear sight to where you want the bullet to GO.


These are akin to what we call in physics... "elegantly simple laws" :D
 
I was at the range last Sunday sighting in a Glenfield 60 and a 25. I had just put some peep sights on both. It gets confusing but when you think about it, its very simple.

Move the rear the way you want the bullet to go. I always make sure my front sights are centered(dove tail style) before I begin just as a starting point.

I recommend starting at 25yards and get it on the bullseye then move to 50yards and dial it in some more and eventually working your way out to 100yards. For my Win model 94AE and peep sights I like to be able to hit a paper plate at 100yards, thats good enough for deer and the distance I shoot around here
 
If your spatial reckoning allows you to, note that you are actually moving the barrel in relation to your line of sight. which remains fixed from your eye, through the sights, to the target. (I have run that idea at several people, some who had an "OH! Yeah!" moment, others who were baffled even after various attempts at explanation. Many of the baffled are otherwise very intelligent.)
 
If your rifle is shooting to high with the rifles Sight Elevator set on its lowest (bottom) hump. You can remove the (site elevator) for even (more) lowering of your bullets impact.
Had a couple rifles over the years that to shoot properly required their Rear barrel site to rest on the barrel itself.
