Lee Enfield Micrometer sight question

[plinker 777]

Gun nutters; I've gone full wood on a scoped No4Mk2 sporter,took the scope off and installed a micrometer/diopter rear sight.
I had it at the range today to zero in the front sight,started at 60m battle sight and zeroed it in. I shot at the 100m target I had placed earlier with battle sight to conferm zero...it was. I the fliped the micrometer sight dialed down to 200yards,expecting to hit the paper perhaps and inch or two high of zero and miss right over the target, tried again and same,over the target I fliped back to the battle sight and it was fine

So my question is, Is this normal? I would have thought with a 303British the rounds at 200yards would be a fairly flat trajectory. According to the rifle, I would have to bring the muzzle down 8-12 inches to use 200yrd sight at 100meters.
Any help would be appreciated. Thanks......Plinker

Its not a 60m sight, its 600 meters. Are you sure you went over & not under?

What bullet weight and velocity were you using? The stock sight is calibrated for a 174 gr bullet at 2440 fps. Also, the 'battle sight' is designed for 'minute of bad guy' combat shooting, aimed fire really doesn't start until 200 yards with the LE. There is some evidence to suggest that 200 yards is the closest range that you can predictably target shoot an LE at, the bullet isn't properly stabilized at 100 yards.

Just a small point, on a No4, it's YARDS, not meters. And enfields are inch pattern, NOT metric. For that matter L1A1's are also inch pattern. I don't know about the current rifle.

If you want to use the Mk. I rear sight, and have the calibrations relate to the actual range at which you are firing, you will have to zero the rifle by exchanging front sights until the elevation is correct. That is, when the sight is set for 200y, the bullets impact at the correct point in the 200y target. The Mk. I sight adjusts below 200y, but there are no calibrations. If the rifle is zeroed at 200y, point of impact will be high at 100y.
Military practice was to initially zero at 30y, on a special zeroing target. The group did not form at the aiming point, but rather where it needed to be for the elevation to be correct at the longer range.
I believe battle sight zero was 300y, should be about 7" high at 100y. If you have a 100y zero with the battle sight, the front sight is not going to be correct for the rear sight calibrations.
NFG - a .303 rifle groups perfectly well at short ranges, you don't have to wait for 200y and greater.

Hmmm...I didn't know it went lower{didn't want to bottom the screw threads}. Yes, point of impact was around 7" high at 100m {metric range}.
Can anyone put me on to what these 30yrd zeroing targets look like?
the .303 seemed to group fine at 60m and at 100m I didn't run into issues until I used the micrometer to sight in the 100m target @ 200yrd settiing

Another thing I noticed was when I received the rifle with scope attached the front blade sight was flush on the right side{off center to the left} So when I removed the scope I centered the front blade.When aiming bulls at 60m and 100m groups were consistently left side of bulls {4-6"} So i put the front blade after several adjustments to the left exactly where it was in the first place to group at center of target. Now that I'm thinking about it....The only other center fire rifles I shoot {sks} the front sights are all the way to the left as well....3 rifles all front sights all the way left...common denominator, shooter{me?}.....Am I doing something wrong?
