How to use CDs in air rifle
A suggestion for adding a little pressure to your
training sessions. Take you favourite CD, tape an air rifle
target on top of it (centre precisely!), and fire away. Just
make sure that the pellet goes clean through the centre hole
in the CD...
And look: there's plenty of margin
You see: easy.
The hole in the centre is 15 mm. Effectively, for air rifle
10m this means that you have to shoot better than 8.9. So
just shoot a 9 or better. So don't shoot an 8. Don't even
think about shooting an 8.
So how hard is this anyway. The probability that you
will 'hit the hole' with a single shot can be calculated as
a function of your mean score on a 60-shot match. The
relationship is shown below:
So if you normally make around 500 points, you might
as well flip a coin. And if you normally shoot over 580, it
is in fact too easy for you.
