This target is 125mm in diameter (4.92 inches) which correlates to 1.0 Mil-Radian @ 125 metres, or 0.5 Mil @ 250m.

So... running a Mil-Rad scope / reticle? This target size is perfectly for practising your Mil-ranging.

Don't forget the formula:

(Target Height in Metres x 1000) / Height in Mils = Range to Target in Metres.

Or:

Target Height in Millimeters / Height in Mils = Range to Target in Metres
