.22 at 200metres!

our 200 is 80 feet between the side berms that are 20 foot plus , but the wind blows here most ervery day and any direction is possible , the end berm is closer to 30-35 feet , you can get a lot of mixed direction in that bowl , 

I don't know how much help this is going to be, but here it is anyway.

I have one of those "windage adjustable Lee Enfield Target rear sights". I picked it up as a curiosity when at SARCO years back & its been used as a poor man's ladder rear-sight on my .50 Hawken percussion carbine.

Any way, it seems to be a standard No4 Mk1, Mk1 sight, but modified & with a bracket added for whatever it was used on. The clicks have also been modified by cutting a second set of detents in the adjustment knob.

The original scale on the rear face of the frame is very faint, and  a substitute set is engraved in the left hand side of the frame.

I'm guessing to give 1/2 MOA clicks maybe? Its 4 clicks from "2" to"4" on the old, Presumably .303 scale

I believe these were used on some .22RF training rifles, but not Lee Enfields. Because of that I have no idea of the barrel length or sight radius.

The scale is oddly marked, I assume to get the information in the restricted space of the frame.

From top to bottom

In yards I guess?

20 = 200yds

15 = 150 yds

-   = 125yds?

10 = 100yds

5 =50 yds

25 = 25 yds

? 

anyway its 36 clicks (18" maybe?) from "10" to "20"

I looked at a ballistic calculator yesterday, it gives about 30 moa raise from 50 to 200 metres.

It's only about 4.5 moa for the.303.

I will check how much elevation I can get on the number 8 rifle as well. Make sure I have sufficient adjustment before bringing the rifle.

I'll update after the weekend.

I'd set the sights from the ballistic calculator 60 clicks up from my 50m zero that's 30 moa. My daughter took the first go and was immediately on the paper with two 3's at the top . She had been aiming dead centre, but I set it up for 6'O'clock hold. So after realising, she got into the black, with a nice group in the 7-8 rings of five bullets in a 3" by "5" rectangle ( you can cover them with your phone). She did get one in the 10 well centred. Seeing as she was still generally too high, I knocked off two clicks 

But ended up low and left, but mainly in the black, with a similar sized group of 6 in the lower 7-8 rings , as opposed to her high and right.

But a super fun day despite the sweat! 

The rifle is so quiet, when others are shooting the large calibres next to me, I kept thinking it hadn't fired. But since adjusting the rear of the bolt head, to remove a bit of play from the firing pin, it's been no problem with the Eley ammunition.

Although the CCI is more accurate at 50m, it chronoed at around 995 to 1020. Whereas the Eley was very regular and close to the stated 1060 on the box. Vertical spread was reasonable, although my sideways errors need ironing out!
