:( sorry - distance was 100m, with lowest setting of the rear sightQuote:

The high group surprised me a bit - the previous owner was supposed to be a shooter and reloader. Could also be that he was shooting reduced charges only?:confused:
Actually, somewhat lower than standard velocity rounds (assuming ~174gr projectiles) often strike higher at 100m. But 9-10" (~23cm) high is a bit much! You would have to know what rounds he was shooting- 123gr,150gr,174gr,180gr and at what velocity.
The sights will go slightly below "2" (200yds) but if it was set at "2", then you would expect impacts about 3" high at 100yds (about the same at 100m).
Are you shooting the ammo which will be your "standard"? If not, then a re-zero at this point may be counterproductive.
Actually, it's easy math to sort out the blade height change at this point- Except I don't have an SMLE at hand right now (at work), and I don't remember the sight radius! If you can measure from the rear of the front sight to the rear face of the rear sight, all the other info is known. Metric on English- whatever units are easiest- but the sights are marked in inches (we'll guess yours is a standard height- marked "0"), so that's gonna be the most useful for our purposes.
Hokay, sight radius is about 19 7/6" as measured off a spare barrel. (quicker than breaking out a complete rifle!)
So, making everything in inches, and with a bit of rounding:
x/19.44=9.5/(39.37x100)
x=(9.5x19.44)/3937
x=~0.047" tall front sight.
ETA: Good deal! As it's pretty close to a standard size, you need a +0.045 sight if you don't change anything (including lighting conditions and the weather!).
See the link below for Simon P's chart (Post #25):
-.060 Blade, foresight on a Lee Enfield No 4 MK 2 rifle !
ETA2: the "0" on your sight is likely the size- "OA" would be an Australian manufacturer's mark.
ETA3: If you have the opportunity, check the zero at 200m with the sight set at one hash mark up from "2" -nominally 225 yds- before finalizing your sight choice.
Just for "first feeling" i tried some (more light) Loads / loading data without any guarantee:Quote:

Yes, I assume that the standard ammunition also may be something in this direction. POI change was minimal through all charges.
Thank You very much for Sight-calculation-ABCQuote:

Allow me one (beginner:o) question : what means 39.37?
I have at this time only the 100m range available.
...jmoore - thaks for Your patience!:beerchug:
EDIT: I just found this one . OK, it is to high so some rework would be needed. Advantage is thickness (my eye don't like the thin SMLE Blade too much)
1 meter = 39.3700787 inchesQuote:

Peddled Scheme contractor for Stock buts was, among others, also the company E.J. Riley.
Citation from this Page:
".... The fateful year of 1914 saw the capital increased to 1120,000, but in August, the war started and the machines were turned over to war work, with Rifle Butts and Aeroplane Struts being made instead of billiard tables..."
So could i assume that my SMLE Butt was made by this company - E.J.R. Stamp??
The L&C (or L&G, L&O) on Buttplate - could that mean Linley & Co. ? Also a Peddled Scheme contractor?
:confused:
Front sight blade... Is it jut dove-tailed or somehow additionally secured? I can't remove it .
I don't have the front sight tool - but with hammer & brass pin punch - it wont move :crying:
The front sight blade SHOULD be merely dovetailed and held by the interference fit. Could be staked in place additionally, but that ought not defeat a larger hammer. (Make sure the base is well supported before impacting the sight at it's bottom at the dovetail area. The assembly may just need a bit of extra force to get moving for the first time in 50-60 years! Once movement has started it ought not take as much force.
I DO recommend using a larger hammer. High velocity blows from a too small hammer will likely peen the metal in a localized area rather than merely causing the sight to move.

Yea! Larger Hammer helped (like in most "technical problems"). I was just to careful - I was afraid that I'll break something.
Thanks for help! :beerchug:
