I don't want to bugger up an original, so, no scopes.
I'm shooting about 2' (that's right, FEET) high at 100 yards.
For those not familiar, the Ross rear sight has no ability to go lower.
It has the full length close to 30" barrel. How high a front sight do I need?
And I'm guessing I have to make one right?
 
are you using the 'battle sight' or are you 'flipping up ' the sight and using the peep?

The battle sights are set to 3-400 yards (I think)...the peep sight can be dropped to 100 yards
 
You will need a front sight about .25" higher. Is the rear sight adjustment bottomed right out?
 
I'm in the same boat. My mk2, with 30" barrel, shoots about 2 feet high at 100m with 180gr bullets. The Mk 2 Ross was designed to use the Mk6 round, which was 215gr.

I know it's a tall order these days, but try finding heavier bullets.
 
I'm surprised that the sight won't adjust down enough. You are using the aperture in the leaf, and not the notch? On my Mk.II***, the rear sight will adjust down to the point that the rear handguard blocks the view of the sight. If its a couple of feet high at 100, its still going to be high at 200. These Mk.II Rosses were intended for the Mk.VI bulletm but the supply of 215s is thin. A front sight high enough to give you a 100 yd zero isn't going to go under the sight hood. I've used 180RNs seated way out in my Mk.II**. No zero problems, but the rear aperture sight is a BSA Martin, so there is nothing in common with a New Glasgow sight.
 
It was a while ago, but I remember it was pretty close at 200m. Maybe it was 1 foot high at 100. As for sights, I tried it both ways: with notch and with flip up. Since then I've been using my mk 3 and my Enfield. I was going to test it (the mk 2) some more but I just never seem to get around to it. If I can find some 215gr, I will give'r a go again.
 
I'm no expert on the Ross but I agree with what Klunk is saying regarding the use of the sights. It took me a few shots to figure out my P-14's battle sights.

Other then that peek down the bore to see if the barrel is bent upwards.

It wouldn't take much of a bend to produce what you are seeing.

If it is a bent barrel it is fixable in the hands of a skilled gunsmith.
 
All other things being equal (barrel is straight, rear sight won't go any lower), you need a higher front post...
 
When shooting the MkII Ross it is advisable to slug the barrel . All MkI ross and MkII ,*,***,4* and early II** have a .299" bore and a .309" groove size.
 
Which suggests that .30 caliber bullets could be suitable for many. 220 RNs could be a substitute for the 215s. My II** is a later one, and is definitely .303 bored. Have yet to slug the 1905R sporters. I suppose that it might be necessary to adjust neck sizing for .308 rather than .311 bullets.
