Finally, my Enfield collection has a loud-mouthed shorty to round out the team - Got meself a beautiful Faz made in Jan47, and got her up to the range yesterday for a few thunderclaps in the falling snow.

Two minor issues: POI was approximately ONE FOOT low at 100m with the micrometer set at 200yards... So, after I verify that with another brand of ammo, I'm going to be looking at a front sight that is... four sizes shorter? (One blade difference should be about 3" POI shift, or am I mistaken in my recollection?).

Also, and don't laugh... I have rather long arms, and the little butt was almost workable with my winter coat, BUT... Kept poking myself in the snout with my bloody thumb, and I wonder... Is there such a thing as a LONG No5 butt anywhere? Repro, or original?

Thanks, and best tidings of the season to all!

If you are using a light bullet...try a much heavier one and you may find the sights work out.....orig. loading for the .303 was 215gr. RN @1800 fps and your sights may be set for that(the orig. BP loading) or the later 215gr. smokeless load of around 2200fps. M.T. Chambers produces the 314299/205gr. cast bullet which works well to try and duplicate orig. trajectories and is easier on the barrels and your pocketbook. Sometimes cast bullets are more flexible than the j-word.
 
Neal,
What brand/type of ammo where you shooting?

I have seen long No5 butts on rifles, never for sale separately.

Edit: Ben, A No5 is sighted for the Mk7z Ball ammo.
 
The ammo was 174gr Remington UMC FMJ... which is close as I can see to the original MkVII ball, which, I believe would have been the service ammo intended for a rifle produced in 1947...?

If it's shooting low, just move the rear sight up another couple of notchs till it's where you need. It never really mattered to me to have the rear sight calibrated to the shooting distance. I only shoot at 100 and 200m with the irons anyway.....
 
My No5 has to be dialed up to 400yd to hit POA @ 100yds with various loads dancing around the MkVII specs. I posted on here about it and I wasn't the only one. Is it grouping ok?

If other ammo that approximates ball ammo prints the same, in my opinion you're on the right track to adjust by changing out the front blade rather than faking it at the rear sight. Front sight blades are easily found.

If there ain't, it shouldn't be too difficult to fit a No4 long butt.
 
Thanks again, everybody, for responding. I must have been a bit vague in my original post, as no one's actually answered my question about sight blade heights yet:

What difference in POI does changing ONE sight blade height make at 100 yards? I THINK it's three inches, but I have forgotten!

(i.e. - With my rifle apparently grouping 12 inches low, with a .060 blade, would changing four sizes down to a 0 work to bring me up?)

Cheers,

Neal

only 1 way to know :D

I don't know what the change would be on a No5, it has the shorter site radius so the change is more then a No4.

one of the other enfield experts will know. If not I'll dig out the book tommorrow.
 
According to Equipment Description, Rifle, Calibre .303, No.4, All Marks, With Equipment, there are 12 sizes of front sight available for the No.4 rifle (I don't think the f/sight blades are interchangeable with the No5, but I could be wrong about that, but the No4 blade is held in with a screw, while the No5 blade is a split dovetail), with the shortest overall height being #1, and the tallest overall height being #12. Your .060" front sight blade is #8, so there are 7 shorter fr. sight blades available in .015" increments down to -0.045 (or 0.275" overall length, from bottom of dovetail base to tip of blade: your .060" blade is 0.380" OAL).
I don't have a chart that shows the effect of the different front sight blade heights on POA/POI, but I'm sure a "MOA Guru" can do a quick calculation for you. :)
Ok...edited to add: I found this info for the No4M1 rifle:-

Each change of foresight to the next size, up or down, will change the MPI, up or down, 1/2 inch at 25 yards and 2 inches at 100 yards.

HTH!

Does your carbine have a no 4 sight on it ? that would be the first thing to check. I think you sight should only go up to 600yds could be wronf though.

As for how much more sight bade hieght you need, do the math (Stay in school kids). Seriously though if you have a load you are going to stick with then do the math and then you will know exactly what you need to add in height.

You're wrong. :p The No5Mk1's rear sight is graduated to 800 yards.

Care to share the "bade hieght" math, professor?:D
 
Yes, it IS a No5 sight, graudated to 800 yards.... And, for those that need to do extra reading practice about the aforementioned details.... The rifle is hitting LOW, thus the FRONT sight needs to be SHORTER to RAISE POI.

Hard to do the math if you read the word problem wrong(!)

;)

Six Star... Thanks for the info about ~ 2 inch change in POI per blade height adjustment! That helps!

Now, if I could just find a longer butt.... Gosh, I suppose this might actually be a reasonable excuse to add a slip on recoil pad....(!)

For a Kick like a mule Number 5 this would have been the first thing I would do. :D
 
Why bother getting another sight blade, just file down the one that's presently installed until it's zeroed where you want it. There is no need to remove it from the rifle.
 
Found this on the bottom of http://enfieldrifles.profusehost.net/ti15.htm It all seems to be here under "marksmanship" on this page: http://enfieldrifles.profusehost.net/ti.htm

The No5 Rifle (Jungle Carbine)

Zeroing at 25 yards the Mean Point of Impact (MPI) should be 1/2 an inch above the point of aim (POA).

Zeroing at 100 yards the MPI should be 3-1/2 inches above the POA.

The method and sequence for correcting elevation and windage on the No5 remain the same. However, the following differences apply:

Elevation: each blade height (.015) alters the MPI by 2-1/4 inches at 100 yards and 1/2 inch at 25 yards.

Windage: each blade width (.050) alters the MPI by 7-1/2 inches at 100 yards and 1-3/4 of an inch at 25 yards.

The standard No5Mk1 buttstock is ideally proportioned for normal sized English people, and I find it to be perfect in length. :D:p
I believe I have seen repro JC parts, including longer stocks somewhere....I'll see if I can track one down.
