Target height shooting range

We are creating a blueprint for a new smallbore rifle range 50mtr equipped with Meyton shot-measurement. Because we want to make the range "Olympic approved" we want to have the target's on the correct height. The ISSF states: 0,75 meter (+/- 0,5 meter). This means a difference of 0,25 - 1,25 meter.
What's your experience in this? Which height do you use (for all three positions)?
Thanks for your reply!

We just built a 50m range last year. The target height had to higher than 750m (about 1050mm) as the ground sloped up to the targets. We did raise the firing point to help keep the range within ISSF specs.
One point to consider is that you will have less interference from mirage if you have the sight line as high as possible above the ground, esp important in dry conditions as mirage makes good scores more difficult.

Check your math, and you will find the correct allowance is .7M to .8 M (or just under 4 inches).

Sorry but you need to check yours.
For 50m ranges rule 6.3.9 clearly states a target centre height above the firing point of 0.75m +/- 0.5m. This is obviously 0.25m to 1.25m or 9.84inches to 49.21inches, a difference of 39.37inches (1m).

Sorry, I misread your 50M as 50feet.

Go for the 0.75m if possible; after all, that is the specified height. The +/- 0.50m is there to allow for:
- 'difficult' sites, and
- existing ranges built to old specifications.
What do you mean by "...Olympic approved..."?

Olympic approved means that it fits the international standards. So don't worry, I was not planning to organize the Olympics on our club! (with a max of 10 ranges.......) ;)

It's easier in the long run to make your range as 'good' as possible.
The 5m between the firing line and the spectator barrier is starting to show its age - 5m is not much for rifle shooters, their gear, and any EST printers etc. My friendly advice is don't scimp on this,
Best of wishes for this project,
