1. ## Minutes of Angle

I understand that a scope that has 1/4" clicks means that 4 clicks equals 1 MOA @ 100yds, 2 MOA @ 200 yds (roughly)

My swarovski is 1 click = 0.36" @ 100 yds, am I right then that trying to calculate come up etc is virtually useless on this type of scope.

2. A Minute of angle is a 60th of a degree. A 1/4 MOA is a 1/4 MOA regardles of the range. A 1/4 MOA represents roughly a 1/4'' at 100 yrds so 4 clicks up, for example, will shift the next group up by 1 inch at 100 yrds or 2'' at 200 yrds. This is the theory, in reality, the best thing is to use it as a guide then check for yourself on the range. This is easier to do at longer range as, if you are looking for a 1 inch change of MPI but shooting 1-2'' groups it all becomes a bit pointless. As for your Swarovski, just consider 1 click to represent 1/3 MOA and work from there. JC

I think you can calculate come-up's with this scope: 3 clicks will move you one inch at 100 yards.

4. Thanks for the tips, its clearer now, I found this which seems to simplify it even more.

5. Hi

I suspect that the swarovski is calibrated in 1cm at 100m increments. This is the same adjustment as 0.1 milradians ie 1 milradian = 10 cm at 100m or 1 metre at 1000m.

Personally I find the metric system far easier than MOA, particularly if you have a reticle such as a mil dot that is graduated in milradians. It just takes a little of getting used to.

6. HI

Just a passing note under EU regulations 1234/347854/hf6/87/2010 Para 4 it is illegal to shoot a firearm in the EU either in the field or the range using imperial measurement on you optical aiming devices or trying to convert a scope that is metric to shoot imperial groupings

7. Minute of angle is 1.047 inches.

8. http://www.biggameinfo.com/BalCalc.aspx

just put 3 in the clicks per MOA box. should be near enough

or try it on paper and build your own chart

9. Gentlemen 0.36" is 9mm or very close to 9mm. 0.39" is 10mm.

10. Hi

I think the minor difference may well be the difference between 100m and 100 yards

ie 100 m is 109.36 yards and so one click will make a slightly larger adjustment (9% more) to the point of impact. This equates to 0.39 inches per click at 100 metres which is the same as 1cm clicks.

Easier to work in metrics with this scope I think

Cheers
