Re: yards or meters
Hi Trevor, if you want to shoot in a match (such as at the Okato rifle range), the range will be 1000 yards, same as other competitive ranges around the world. If your scope and drop charts are calibrated in meters, you will have to make conversions on the fly.

I grew up with the SMLE .303 rifle, the sights were calibrated in yards. I also learned that my casual pace was 1 yard and that to pace out a meter, I had to stretch my pace right out. So personally, I kept working with yards as this was the most natural form of measurement for me.

Inches/ Imperial units were easy to use as I could utilize areas of my hands, reading finger joints to make smaller calculations. We grew up with a 30cm/12" ruler so that was also easy as for very fast estimations, I could picture a half a ruler, a full ruler or twice a ruler etc.

Back then, for long range shooting, I had to use NZ topo maps and a compass ruler. The ruler on the compass was in meters so if I set myself up on a ridge, I had to do conversions back to yards. So although I had my system in place which worked in well with U.S literature, I still had to do some conversions until the advent of laser range finders available in either imperial or metric.

Ok, so thats one aspect. The third unit of measurement which I think you really need to understand as being very useful, is minutes of angle. MOA is neither metric or imperial but rather, a military standard, used by Artillery regiments. In its very basic form, the units of measurement are in laymans terms taken from a circle divided into 360 degrees or minutes.

A scope with its turrets calibrated in MOA combined with a modern software programme calibtrated in MOA is very easy to use once it is understood. Dialing up 6MOA is a lot less fiddly than coming up 16cm on a metric calibrated scope, atleast it is to me.

A fourth unit of measurement is Mil dots which divides MOA into another set of units. Mil dot ranging can be used where no range finder is present (when the batteries go flat!). There are systems such as the mil dot master to make mil ranging a lot easier. I tend to use mil dots for windage, I never dial for wind as the wind is such a variable thing. Mil dots can at first seem intimidating but further down the track, they can add a new dimension to your sport, something new to explore and enjoy when you are ready- not something to be intimidated by at all.

If you go to the 7mm Practical article and look at the video of the goat shot at 1125 yards, that was a 1023 meter / 1km shot. The scope used was calibrated in MOA, the range finder calibrated in yards. If that range is the sort of goal you want to achieve, you will achieve it. It will require effort and personal discipline no matter which way you go, whether you use metric, imperial or MOA units of measurement. Drop is relatively easy, obtaining desirable rifle accuracy is a bigger challenge combining an accurate rifle platform with optimum technique. Finally, the greatest challenge is reading the wind.
