Reading targets - Part 2
by B.B. Pelletier
A pinwheel is the perfect removal of the exact center of the bull. It's most dramatic on a 10-meter air rifle target shot with a .177 wadcutter because the hole is exactly framed by the 9-ring.
A flyer is a hole that is clearly apart from the central group. There are many reasons for flyers, but they always represent a fly in the ointment of good target shooting--so they aren't welcome.
Stringing is when the group resembles a line, rather than a circular dispersion. It's caused by many different things, but it's always an indication of something going wrong.
9: One-hole groups
A "one-hole" group is just that--a group in which there is only a single hole. Some interpret this to mean that the hole is the same size as a single pellet, but that's not always the case. Since caliber-sized groups are more theoretical than possible, they should be explained with additional terms. One hole means one hole--regardless of the size.
Calling your shots
We "call our shots" by referring to the target as if it were the face of a clock. This is a standard form of communication that all shooters use.
