Enfield Sighting Problem

Hi,

I took my "new to me" Enfield #4 sporter out to the range yesterday and I have a problem. I believe it's a Parker-Hale, with a 20" bbl and windage adjustable front sight and flip up/battle sights.

Here's the problem:

At 25m, using the flip up sight bottomed out, it shoots about 6" high.
At 50m it also shoots 6" high.
Then, when I brought it out to 100m, I was having a hard time getting it on paper. After putting up the biggest target I could find, a human silhouette, I discovered that it was shooting Way high, like 2 feet. Aiming at the bottom edge of the silhouette, it would hit at the top of the chest on the target.
My buddy and I were stumped, as theoretically, shouldn't the 100m shots be 1" high given the 20m and 50m results? I thought maybe I was doing something wrong, so I handed the rifle over to my buddy, an experienced shooter, who had the same results.
How could this be?
I know my options are: increase height of front sight, lower rear sight (I could remove some material from the bottom of the moving aperture piece that would allow it to move down further, maybe 3-5mm, although this may not even be enough to solve the problem).
Or get my self a mount and scope it. But I'd rather not spend $250 scoping a $250 rifle that Should shoot well with the peep sights.

I'd just like to know why it's defying my trajectory charts. Am I overlooking something?

BTW, ammo was Rem Corelokt 180gr, and Bosnian stuff, both shot the same.
Groups at 50m were excellent, for me anyway, so I'd really like to figure this out and make this a viable deer gun.

Your help is appreciated. Steve
 
If it is shooting 24" high at 100, the front sight would have to be just over over .200" higher, to get a zero, if my geometric calculations are correct. Most of these sporters have a ramp fitted to the barrel, with a dovetailed front sight. Don't know if this would be a practical alteration. Might be necessary to change the ramp.
 
You are correct. The front sight is a ramp w/ dovetail sight. Changing the ramp would be a pain, but perhaps I could find a replacement sight insert that would be high enough. However, that would be one seriously tall front sight and would look rediculous. I was just looking at the rear sight and I don't think I could really do too much with it. Any idea why it would shoot 6" high at 50m and 24" high at 100m? Doesn't make sense. Seems like a scope may be the simplest solution. I'll try to fashion some kind of extension for the front sight out of aluminium and see how that works first.

Is your flip up sight two position or does it adjust. if it does not adjust it is a flip sight that is calibrated for 300 yards and 600 yards IIRC.

Get an adjustible rear sight and yer done. PM me, I may have a beater sight you can have fer free.
 
Hi SKS,

The rear sight is an adjustable micrometer. Even with the micrometer bottomed out it shoots way high. I was thinking of milling some (5mm) of the bottom of the aperture block away, but realized that if I did, my field of view between the front and rear sight would be blocked by the top of the receiver. (know what I mean)?
 
If your rifle is like others which I have seen, the dovetail in the front sight ramp is sized for the original pattern sight blades. Commercial sights are available in a wide variety of heights. It should be possible to open out the dovetail to accept a higher 3/8" sight. Your blade could be made taller by silver soldering on a piece of steel and reshaping.
 
I do believe you are correct. The front sight insert appears to be an "Enfield" insert. The post is 3mm tall. The height of the entire front sight, from the bottom of the ramp to top of the post is 18mm. If I could find an "Enfield" replacement sight insert with a height of 8-10mm, that would fit the bill nicely.
