1" high @ 100 yards?

Yes the open sights on my 8x57 and 9.3 rifles are regulated for and zeroed for 50 metres but if using the scope on the 8x57 rifle I have it set up to shoot the top barrel spot on at 100 yards.

Current zero on my .300 Winnie for Mondays visit is 50 yards.

Yes I should have added that the open sights would be for driven shooting or when the target is likely to be close and the scopes are used when woodland stalking where on my ground the range is normally up to 150 yards maximum.
I'm just imagining the anguish you're having to go through by reading this today. Hope your day starts looking up!
Are you excited...?
, Tim, been counting sleeps mate.
50 Yards is all I need next week, in this stuff,
Apologies for the hi- jack
Have you said that in all the other post you have hi-jacked with your trip..Apologies for the hi- jack
For the OP re zero, I set up a very fancy swro for a friend on Wednesday on his .243, the left to right was good out the box but it was low. Good at 25 yds with 100 just under 1" @100
Why 25, he has a new rife new scope new sticks. but at 79 he did just fine.

When I bought my first c/f, God’s own calibre, the sainted .222, just after the last Ice Age, I pushed the boat out and bought Sako ammunition which I found to be excellent and only when I started reloading did I stop using it. In the ammo box was the attached info sheet which I kept and have referred to as a great guide on many occasions since. Worth a look and settled many a “full and frank“ discussion on a number of occasions since. Also interesting to compare their figures on for example the .270 and .308 but of course a sensible chap would not wish to be so bold….
Just remember, being from where it is they use these strange joules/metric thingies.

With most rifles if you are just a touch low at 50 you are then an inch high at 100. However it does depend on calibre, rifle and how high your sights are off the bore. Have a play with a ballistics calculator and you will get the idea. Hornady have a goid one on their website.
I would always start to zero a rifle at 25 or 50. Get it shouting to point of aim, and then take it out further to check its correct.
With a 50 zero you want the bullet to be still on the rise so its first time it crosses the line if sight, rather it being the peak or even the 2nd crossing.
And knowing where your rifle shoots at 50 is always very useful for checking your zero.

Agreed, most folk on here go: 'Me zeros me rifle an inch 'eye at 100, all fyne out to 300!' then later sheepishly admit they later missed at deer by shooting low.
I once lent someone my Leica rangefinder (mistake #1) and was later told it was off ( it was not), I had it set to meters and they were not mentally pliable enough to realise it was not set to measure in yards.
Be precise and clear, state if you are using either yards or meters, check your zero in 50 meter increments if using a rifle with a muzzle velocity of 3,000 fps or higher, or if using one with less muzzle velocity, check in 25 meter increments. Ambient temperature will also play a part so don't 'zero' in 30 degree Celsius summer heat and pull the rifle out of the cupboard when it is -5 degrees Celsius and expect all your settings to be bang on.
Lots of variables to think about: Muzzle Velocity, Bullet Weight, Calibre, Usual range distance.
I would say that c3inch mid-range-trajectory is what you should think about with most calibres.

Inputting data for my .223 with Norma 50g gives near zero 58yds, far zero 223yds, max PBR 254yds for a 3" kill zone, 1.06" high at 100yds. A handy tool.
