meters vs. yards

If your running some form of mil-based reticle in your scope it's nice to use meters, and most guys will especially if they are running mil based turret turret adjustments. Everything is all into 1/10 so it makes for easy math. if your scope is in MOA it will likely be easier sticking to yards.
It doesn't really matter. Mil isn't a metric unit, it's an angular unit in base 10. MOA is often considered 1" at 100 yards... but it really is 1.047" @ 100 yards.
Mil just regularly works well with the metric system because that is all base 10 as well. For example: 1mil at 100m = 10cm. But it also works the same for yards. 1 mil @ 100 yards = 1/100 of a yard = 3.6"
I sight my mil scopes in at 100 yards because that's what my range is. I just calculate my drops based on a 100 yard zero in my ballistics program and go from there to verify those dopes at distance.

meters vs yards? If you have a milrad reticle is it better to do all your calculations/thinking in meters rather than yards?I'm pre metric in age
I was looking at some non electronic ballistic calculators, offered in yards or metric versions.
Nope, not with an FFP scope. I do everything in yards, inches, MPH, etc... The only thing you need to calculate related to yards or meters is range estimation. For scope corrections, just measure with the reticle and plug the numbers directly into the turrets.
The easiest way to think about it:
1 mil is 1 mil at 100 yards
1 mil is 1 mil at 200 yards
1 mil is 1 mil at 300 yards
1 mil is 1 mil at 400 yards
1 mil is 1 mil at 500 yards
1 mil is 1 mil at 600 yards

And your reticle measures things in mils. So, there is no need to think in inches or cm and then try and convert it to mils if you are using an FFP scope.

MILs are not Metric same as MOA are not Imperial.
Both are Units of angular Measure.
DOPE properly using Mil or MOA values on the turret, then call out corrections on misses using the calibrated ruler in your optic. This way you do not need to assign a Linear value to a unit of angular measure.
Many people say that Mils work better with the Metric system because it is easily divisible by 10... True, but you don't need to unless ranging with the reticle (even then you are not assigning LV to Bullet drop, you are simply assigning MILs instead)
Now... if you are using you're reticle to make rough range estimations on known size targets (or the otherway round known distance / Unknown target size) I use the Metric system as the calculation is easier for me in my head....
Known Target size in Millimeters
-------------------------------------- = Range to target
Mils as read
It can be done using the Imperial system but is not as user friendly as a calculation done in the head (at least for me, i'm dumb)
Once you know the range to Target simply look at your DOPE and then choose the closest value in MIL Come ups you have for the R to T and shoot.
No need to think about CM or Inches that way.
I hope this helps.
If you want I have a bunch of stuff explaining all this a bit better... I will scan it and send it to you if you PM me.

If you are in to inches, yards, etc., it may suit you to do MOA. Mil and metric is easier for some. I like and do mostly mil/mil, ffp and metric......everything is in smaller values.
Some like sfp, mil/MOA, and double or half the mil spacing depending on what zoom option they choose(6-12 or 24)
All that really matters outside of ranging is how many lines, dots or spaces the bullet hit off of the crosshairs, then holdover/under that many lines,dots or spaces and send another or dial up/down that amount of lines,dots or spaces and send one.
Don't over think it or complicate it with math and measurements if you can, just use the reticle like mentioned in previous posts.

Canada... maybe either M or Yards... US, all yards. If in M to yards, mutliply by 1.1 and call it done. All my drop charts are in Yards.
Look up the dope for that distance, dial and shoot. For the most part, a miss is likely left and right vs up and down. Use the reticle like a ruler and just move over to put the impact on the target. Shade up or down as needed... Send it.
There is no math involved as I don't think you have time to play with the turrets to center the reticle on target... maybe you do??? I likely will not... just hold off using the reticle.. so much faster, far more intuitive and given that you are moving and changing orientations, the firing solution is going to change constantly. Slow to turn knobs (except elevation) for windage and if you go the wrong way, that is where the fun starts.
If there is a pretty constant wind value for the bottom of the wind velocity, I will dial that in at the start then adjust using the reticle as needed. For F class, we have time to dial everything into our scope but I just don't see that being practical in dynamic events.
