The double rifle I recently purchased (470NE) is shooting a bit low at 50 yards and I would like to fine tune it. At 50 yards it is shooting 3 inches low when the rear iron sight is set at 50 yards. When I flip up the 100 yard sight shooting from the same 50 yard distance, it shoots about 1 1/2 inches high. Left and right it shoots fine. I would like to fine tune it a bit. From what I understand, I need to move my rear sight higher to make the needed adjustment. That said, I'm not sure of exactly how to do that. I do see a small screw that is exposed once you lift up to use the 100 yard rear sight. Is this screw one that would adjust the sight itself or does it just hold the sight on to the gun? The front sight only seems to have the ability to move left and right.

All of this said, would I be better off just to use the 100 yard sight and be satisfied with the gun shooting 1 1/2 inches high?



"If the bullet is not hitting where you are aiming, you must move the sights to correct the problem. Moving the front sight up will cause the bullet strike to move down, and vise versa. Moving the rear sight up will cause the bullet strike to move up, and vise versa.

Moving the front sight left will move the bullet strike right, while moving the rear sight left will move the bullet strike left.

In short, the front sights are adjusted opposite of the direction you intend to move the bullets impact, and the rear sights are adjusted in the same direction."

Vic,

Replace the front bead with a lower one. This has the same effect as raising the rear sight (which on most doubles is not adjustable. There is a table to determine the needed amount of change in front bead height to move the point of impact the desired amount (it varies depending on the distance between the front and rear sights).

mbogo 375 is correct.
However you might try the following. Some times I find when testing an iron sighted rifle on paper I take a different look at the front/rear sight alignment than I do when shooting at animals in a hurry. You might try getting some animal targets [deer are the easiest to find] and shooting at them from field positions. I usually find I shoot a little higher offhand and kneeling than I do at the bench or prone. I would try this before I modified the sights, after all there are not many benches in the field.
Also in my 450 No2 I dropped my powder charge 1 grain and it improved my grouping at 100 yards and raised my point of impact to the sights.

Replace the front sight with the next lower sight. they are marked on the bottom side is one alternative, or have someone install a much larger bead ont he existing sight, that should bring it up 3 inches...or just replace the rear sight and cut the one standing to match your 100 yard sight..

Another good option, and it sounds funny to some, but if you try it and shoot it you will flat out love it...and that is to order a .007 high NECG partridge gold faced post, and use it like a pistol sight flush with the top of your existing sight, and file it down to zero as you shoot it at the range..It is fast as any iron sight can be, and super accurate, every bit as good as a peep or receiver sight in every way..this was an old Texas Ranger trick and it sure as hell works great on double rifles...your eye just puts it there flush with the top and automatically centered, like it does with a pistol, but with a rifle its much easier to hold...This is especially good for old and tired eyes, but works for most everyone that has an open mind on these things....

Lots of options and for the most part, they all work.

Sounds good to me, Jim. Earlier today I spoke with the dealer where I bought my gun and he was very glad to try and help me add a new front sight, or adjust the ones I have. That said, he felt that that to do the job at its best, I would need to be with him while he makes the changes. As you know, many people see or use their iron sights differently. As a result, he thought that it might not be best if he did it all for me. That said, if I decide to let him do it, the chart in your catalogue might help us a bit.
Before I send the gun off to let him work on it, I'll consider opportunities to get it adjusted by a gunsmith nearby. I wouldn't think that this would that complicated...
Thanks again!
