QUESTIONS & ANSWERS
Shooting Terminology
Q
I am new to the shooting sports,
and my background is in aviation.
In my field, the acronym " MOA "
means " Military Operations Area. "
When Air Traffic Control informs us
that MOA is " hot, " we do not fly, and
a " cold " announcement means we can.
Does this terminology cross over to the
shooting sports, and what is " DOPE? "
A
In shooting, " MOA " is an acronym
for minutes of angle. The NRA definition
is, " An angular measurement
method used to describe accuracy
capability. A minute of angle is 1/60th
of a degree, and subtends 1.047 " at
100 yards, which, for practical shooting
purposes, is considered to be an inch. A
minute-of-angle group, therefore, would
measure slightly more than one inch at
100 yards, two inches at 200 yards, etc. "
From a shooter's perspective, " dope "
is a useful and descriptive word when
applied to the activity of achieving
downrange success. This magazine has
used the phrase " Dope Bag " since at
least 1921 when Col. Townsend Whelen
first titled his column. Even then, it
had been in use for years, referring
to a sack used by target shooters to
hold ammunition and accessories on
the firing line. " Sight dope " also was a
traditional marksman's term for sightadjustment
information, while judging
wind speed and direction was called
" doping the wind. " Some shooters also
use it as an acronym for " Data On
Previous Engagement. "
