TargetTalk

I recently bought a new scatt system and want to practice 50m on it. My problem is that practicing on a target centered at 75 cm high seems impractical at a distance of 8.7 meters (The maximum I have to use my scatt).

Is there a formula that can be used to convert the distance/height ratio? As my math skills aren't quite what they should be I was hoping someone here could help.

Thanks

Measure the height of your barrel when in position. Now, subtract that from 75cm. That gives the difference in height between your barrel and the target at the full range.

Now, divide 50m by your practice range. I'm going to be really convenient for myself and say it's 5m (Because damned if I'm looking for a calculator at this time of night). So you've got one tenth the distance. Therefore, the height of your SCATT target is one tenth the difference between your barrel height and the 50m target height.

So if your barrel height is 30cm and your range is 5m, the difference between your barrel height and the target is 45cm at 50m, therefore 4.5cm at 5m, so your target centre should be at 34.5cm.

Most people suggest measuring your sights, and for ease the rear sight is the best point to measure from. Probably doesn't make a massive difference though.

And also remember that the target can actually be at 0.75 m plus or minus 0.5 m. So the target could be at any height between 0.25 m and 1.25 m. It is probably worth training with the target at a variety of heights within the allowable range, so that you have processes for dealing with the possible variations. For example I have just come back from Bisley where my daughter was shooting in the Junior International, the 50 m targets on the Malcolm Cooper range at the Lord Roberts center are rather near the upper limit for example. Shoot on Gehmann boxes on a level range though and they will be down at 0.75 m.
