DONT LAUGH this is my first go round on this Mil stuff. Bought this last week and im fairly confused now. All my Swarvosky scopes have inch incroments and this thing has mils? it is super clear and bright at night and I have it sighted in at 100 dead center at the zero stop now. How many "clicks" (roughly) will I need for 2,3,4 and 500 yards? I need a good website link to figure this out. Ill make a chart after I figure it out. Gun is a short 16.5" 6.5cm shooting 100gr varmint bullets. No idea how fast they are. I haven had time to put the magneato speed on it yet.

The easiest thing to do when shooting a milliradian scope is to switch all your measurements over to meters instead of yards. Then everything will make sense to you. At 100 yards 1 mill is a 3.6"s, but at 100 meters it is 10cm. Make sense? If you are using MOA, 1moa = 1" at 100yards, 2" at 200yards, etc. With millradians, 1 mill is 10cm at 100 meters, 20cm at 200 meters, etc, etc. So just switch the units on your ballistics calculator and range finder over to meters, and the units will make sense real fast.

100 Yards3.6 Inch100m10cm

I don't switch inches/yards to CM/meters, and every scope I own is MIL.
Each .1mil click or hold is .36" @ 100 yds.

You need your bullet BC, fps, and atmospheric conditions to predict drops. There is no "one size fits all" answer.
Input this data into a ballistic solver program, and just dial/hold drops in MIL.

MIL (MRAD) and MOA are just units of measure.
1 MOA is 1.047" @ 100 yards. Or .26175" per 1/4MOA click.
1 MIL is 3.6" @ 100 yds. Or .36" per .1MIL click.

Then there is IPHY (Inches Per Hundred Yards). True .25" clicks @ 100 yards.

There is also technically two measurements of MIL/MRAD. Standard MIL/MRAD and NATO MRAD. NATO MRAD is a slightly finer adjustment, but almost never used in riflescopes. Older version of March used NATO MRAD until they made the switch years ago.

Then, you have the scopes that do not actually track correctly. Most scopes are not 100% accurate with their adjustments....


Good luck.

I knew all that. I was looking to make a chart AFTER i get is on paper at said distances. Im never going to change altitude or have any wild swings in temp. I know enough to know I don't know how to dope a scope at 7500' and then shoot it again at 2500' the next day.

Ok that makes sense. I was trying to convert mils to inches and it was giving crazy head. Im good for tonight out to 150 or so. ill play with it more out to 500 next week.

Jbm ballistics is free on line but you will need some basic info.You will fil in the blanks , select mils then it will give you the solutions.You then go shoot and verify your data.Once verified you can aways change your inputs and your corrected data for any situation, temp , wind, elevation.Hope this helps.

Yeah trying to do the conversion math is begging for a headache. So keep it simple; a mil is 1/10th at 100 of anything.

It's 1/10th of a yard at 100 yards. A yard is 36 inches, a tenth of a yard is 3.6 inches. A mil is 3.6 inches at 100 yards. A tenth of a mil is 0.36 inches at 100 yards.

It's 1 yard at 1000 yards.

It's 10cm at 100m. It's 1m at 1000m.

It's a palm width at 1000 palm widths.

The 0.1 to 100 ratio is always the answer. The units don't matter at all other than being consistent/ not mixing them up. Mils work perfectly in metric or imperial units.

Glad you asked a good question wm51, No laughing for sure. A little challenging to get brain to flip but as LanceKenyon says once you understand it's quite easy and like he said I've switched almost all my scopes to Mil's. Stick with it and you'll be glad you did. Good shooting

It seems you should have asked yourself these questions BEFORE you bought this scope. Oooops!
