Re: Why Mils over IPHY?
Hi together
first of all, sorry for my terrible english, I hope that you understand what I write.
I don't know the IPHY but I know mils and moa click sistem.
I work in meters (mt) not in yards.
MOA sistem
1 moa is 2,91 cm (centimeters) at 100 mt
1 moa is 5,81 cm at 200 mt (2,91 x 2)
1 moa is 14,6 cm at 500 mt (2,91 x 5)
every time you need a calculators for extract the corret moa/distance
MIL sistem
The sistem is metric
1 mt = 10 cm (centimers)
10 cm are 1 mil at 100 mt
1 mil at 100 mt are 10 clicks of a torret of 1 cm (0,1 mrad) click.
1 mil = 10 cm at 100 mt
1 mil = 20 cm at 200 mt
and gone to
1 mil = 100 cm (1 mt) at 1000 mt (1 Km -Kilometers-)
The sistem work in decimal
If my spotter say me to correct my shoot with 1,3 mils up, I can choose if correct with the reticle (hold off) or with the torret click, in thi second situation I turn 13 click if at 0,1 rad (1 cm). If I and my spotter work with sniper scope and spotter scope both with the reticle on the FFP there aren't problem for the different magnifications between the two optics or not complicate mind aritmetics operations: 1,3 mils are 1,3 mils for both.
The mils system is very fast and simple, but for a good work is necessary that the torret of the scope, the reticle and the spotter scope work and speak at the same language. If You prefer work in MOA the mind aritmetics problem are a lite bit complicate and not so natural. You can speak the same language with the reticle and the torret click but not with the spotter scope, it works only in mils.
KISS
target at 650 mt
1 mil at this distance is 10 cm x 6,5 = 65 cm .....easy
1 MOA at this distance is 2,91 cm x 6,5 = ...... you need a calculator
The MOA sistem is perfect if you work with 1/5 moa, 1/8 moa for bench rest competitions or precision shooting competitions, but if you are a hunter or a military the mil sistem is the winner
Another think, with the mil-dot or TMR or similar you can work great in hold-off at every distance. Last week I shoot at 800 mt with my Remington 700 Police DM with NXS 5,5-22x56 setting at 100 mt and Fiocchi USA .308 180 grs cartriges. At 11x, hold-off at 5 mils down I was in the center of the target. This isn' t possible with MOA reticle.
Sorry, sorry sorry for my english
